BioStamp nPoint User Manual
System Description
BioStamp nPoint is a wireless remote monitoring platform intended for use
by healthcare professionals and researchers for the continuous collection
of physiological data in healthcare and home settings. BioStamp nPoint is
designed to capture objective, real-world data from study subjects
participating in clinical or academic studies, and may be used wherever
collection of relevant data is needed.
BioStamp nPoint centers on body-worn BioStamp Sensors that can be worn
for up to 24 hours at a time in both laboratory (clinic) and home settings.
Investigators (either researchers or physicians) design studies and the data to
be collected using a web-based study configuration tool, called the
Investigator Portal. For laboratory or clinic (“Supervised”) settings, BioStamp
nPoint includes a Tablet Investigator Application (“Investigator App”) to be
used for the set-up and configuration of the sensors. When BioStamp nPoint
is used in the home or outside of the clinic (“Remote”) setting, study subjects
interact with the system through a Mobile Phone Application called the
“Link App.” The recharging and data transmission hub (“Link Hub”) is used to
recharge the sensors and synchronize data from the Sensors. BioStamp nPoint
includes an algorithm package that delivers a dashboard presentation of
processed metrics on general activity (including step count and activity
classification), heart rate, heart rate variability, posture (body position relative
to gravity), sleep, and respiration during sleep. The system is also capable
of surface electromyography and monitoring limb and body movements
during daily living and sleep. Data are transmitted wirelessly from the Sensors
through the Link Hub to the MC10 Cloud for storage, processing, and analysis.

BioStamp Sensors
The BioStamp Sensor is an extremely thin,
body-worn system designed to measure
and record biometric signals.
The Sensor is optimized for small size and low power operation. BioStamp
Sensors can collect biopotential (surface electromyography) and
accelerometry (limb and body movement) data.
Sensor Coordinate System
Sensor Back View
The Sensor can be placed in numerous orientations in various locations, and
multiple Sensors can be placed on a single person. Once activated using the
Investigator App or Link App, each Sensor operates independently, storing
data in its local memory. The data can then be transferred wirelessly for
display and subsequent analysis. The Sensor is designed for use cases
involving up to 24 hours of continuous wear.
Inspect Sensors
Inspect all Sensors for damage prior to use.
Damage includes cracked, split, or broken encapsulation; exposed
electronics other than the electrodes; tears or splits in the device; or any
other deviation from the manufactured state that might impair
functionality. Do not use Sensors that have visible damage.

BioStamp nPoint User Manual
Adhesives
BioStamp Sensors are applied to the body using disposable adhesives for
attachment that also contain hydrogel to optimize electrode contact to the
skin. These double-sided adhesives have a sensor-side and a skin-side and
should be applied to the Sensor using the provided applicator as a guide.
The adhesives are intended to adhere the Sensors to the body for up to 24
hours.
Under certain conditions the provided adhesive might not be sufficient (e.g.
prolonged swimming, very intense exercise) to adhere the Sensors to the
body for the full 24-hour wear duration. The Dorsal Foot and Dorsal Hand
locations are particularly prone to adhesion issues due to the movement and
body morphology of these specific areas. MC10 recommends providing an
additional method of securing the Sensors to these body locations and for
use during certain activities.
Apply the Adhesive Stickers
to Sensors
Each adhesive will be packaged individually in a sealed
foil pouch. Do not open the
adhesive pouch until you are
ready to apply the adhesive to
the Sensor.
Note
20
For locations outside of the required analytics sensor locations
(see Investigator Portal Study Design), extra means to secure
the sensors to the body are recommended (e.g. TegadermTM,
CobanTM wrap).

Proper skin preparation improves Sensor adhesion and signal
quality. Before applying the Sensor, prepare the skin of the subject
by trimming any excess hair at the application site and cleaning
the site thoroughly with soap and water. Dry the area vigorously
before applying the Sensor.
Note
Alcohol wipes are not recommended as they dry the skin,
which reduces adhesion and electrode signal quality.
Additionally, using body lotion or other skin preparations may
interfere with Sensor adhesion.

nPoint (BioStamp Sensor, Link Hub, Link App, Sync App, Investigator App)
contact MC10, Inc.
When new software versions are available the mobile applications will instruct
you or the subject through the upgrade process. For Remote studies, the
software is checked during the subject setup and system reset processes.
Release notes of the changes are available in the app Update menu and
detailed engineering changes can be sent upon request.
Cleaning and Disinfection
The system may be reused across multiple subjects, and reusable components
must be cleaned and/or disinfected per instructions between subjects by the
responsible organization or service personnel. The minimum service
personnel requirements are an 8th grade education and the ability to read
English. Clean and/or disinfect component before any service procedure.
Sensors must be cleaned and charged before initial use. If you remove a
Sensor from a subject and plan to replace it later, clean the Sensor before
reuse. We recommend cleaning the Sensor prior to recharging.
DO NOT expose any component or part of the system to heat above 40°C,
dishwashers, clothes dryers, autoclaves, or other industrial cleaning processes.
Subject
The subject should clean BioStamp Sensors after each use. Simply
remove and dispose of the one-time use adhesive sticker, wash the

In addition to the subject cleaning the Sensors with soap and water, the
Investigator should clean all Sensors and all Medical Electrical
equipment and certain accessories between each subject. To clean,
simply wipe down each component (BioStamp Sensor, Link Hub, Power
Supply, Link Phone, Sync Phone, Tablet, Adhesive Applicator) with an
alcohol wipe (70% Isopropyl Alcohol/30% De-ionized water) to remove
visible dirt and debris or use a cleanroom wipe sprayed with a 70%
isopropyl alcohol solution. Let all components dry, until no IPA is visible.
To further disinfect the BioStamp Sensor, use an additional alcohol
wipe and allow Sensor to dry before reuse.
BioStamp Sensors tolerate exposure to 70% isopropyl alcohol.
The adhesives may interact with residual alcohol, however. Be
sure to allow alcohol-exposed Sensors to dry thoroughly before
applying adhesives.
Note

Run a Remote Study
Investigators can design and run Remote Studies to collect data outside of the clinic or lab. The BioStamp nPoint
Remote Kit contains all the tools necessary to gather
insights from a subject’s daily life or home environment.
Supervised Studies utilize the following components:
Assign BioStamp nPoint Remote Kits to Subjects
To active a subject’s account and assign BioStamp nPoint
take home components for a Remote Study, you will need
to input a key code in the Link App on their assigned Link
Phone.
To generate this key
code, open the
subject’s profile in the
Investigator Portal,
and press the Remote
Password lock icon. This
will generate a 16-letter
code.
35
BioStamp nPoint User Manual
Input this code into the subject’s Link
App to associate the app with the
subject’s study program and assign the
Link Phone to the subject.
This code will also be provided to the
subject for logging in and out of the
Link App.
0-3
Place the Link Phone into the Link Hub dock (that you plan to send
home with the subject) and follow the prompt to assign BioStamp
Sensors. Choose the Sensors and place them in the Sensor pockets on
the Link Hub. If assigning more than 3 Sensors, wait until the first set
of 3 Sensors have been recognized by the Link App and then replace
with any additional Sensors you wish to assign. This can be repeated to
assign as many Sensors to the system as needed.
Note
36
Once all Sensors have been recognized by the Link App, all
system components have been assigned to the subject.

Train the Subject and Send Them Home with
BioStamp nPoint Remote Kit
Remote Kit components are designed for Remote operational
use by the subject. Train the subject on system use prior to
sending the subject home with their Remote Kit and Subject
IFU to initiate the study program.
Subject Study Procedure
At home, subjects will set the Link Hub
on a flat, stable surface, plug the
provided power supply into the back of
the Link Hub, and insert the wall adapter
plug end into a nearby outlet.
Subjects will then charge BioStamp
Sensors by placing them in the sensor
pockets on the Link Hub and will charge
and connect the Link Phone by plugging
into the phone stand in the Link Hub.
When the phone and Sensors are
charged, they will open the Link App and
follow instructions to apply Sensors
(including Sensor position check),
complete prescribed activities, and
answer survey questions.
At the time of Sensor removal, subjects
will follow instructions to remove, clean,
and recharge Sensors. When Sensors are
placed back on the Link Hub for
recharging, the collected data will be
sent to the Investigator Portal for i
nvestigator review.
Subjects will follow Link Hub instructions
until the end of the Remote Program,
and then return the Remote Kit to the
investigator.

to access their data.
BioStamp nPoint User Manual
Under the Data section of the subject’s profile, each recording is listed
by Sensor. Click on the date and time of the recording for a raw signal
visualization.
Plots of raw data versus time can be visualized on the dashboard for
each sensor signal and can be navigated to a specific timestamp,
activity, survey, or annotation. Navigation tools on the dashboard
facilitate jumping to the beginning or end of a recordings, as well as
specific points of interest. The calendar option allows investigators
to visualize the dates when subjects have recordings. The timescales
are dynamic (toggle between 1 hour and 12 hour view) and resolution
options includes 5, 15, 30, and 60 second windowing intervals - as well
as auto-scaling.
Activities and surveys are displayed on the timescale alongside the raw

Programmable Electrical Medical System (PEMS) connection to an
IT-Network
Data is transferred continuously among components during normal system
operation. Raw (unprocessed) sensor data is transferred wirelessly from the
patch to the mobile through Bluetooth LE. When network connectivity is
available, sensor data is transferred from the mobile to the cloud. Once the
cloud confirms receipt of the sensor data, the patch’s on-board flash memory
may be cleared for subsequent recording.
Implemented Protocols
BLE, USB, and HTTP standard protocols are implemented between the PEMS
and the IT-network. These protocols encompass and incorporate the
required characteristics of the IT-network incorporating the Portable
Emissions Measurement System (PEMS), the required configuration of the
IT-network incorporating the PEMS, and the technical specifications of the
network connection of the PEMS including security specifications.
Information Flow
The intended information flow between the PEMS, the IT-network and other
devices on the IT-Network, and the intended routing through the IT-network:
BioStamp Sensor to Link Hub
BLE/ESB
BioStamp Sensor to Tablet
BLE
BioStamp Sensor to Phone
BLE
Link Hub to Link App
USB, Android Open Accessory
Portal to Cloud
public internet, HTTPS
Investigator App/Tablet to Cloud
WiFi, public internet, HTTPS
Link App/Phone to cloud
WiFi or cellular, public internet, HTTPS
Note
54
This can include aspects of effectiveness and data and system
security as related to basic safety and essential performance
(see also Clause H.6 and IEC 80001-1:2010).
BioStamp nPoint User Manual
Sensor to Mobile Communication
Data stored on the patch’s on-board memory is secured through a
proprietary bit packing and memory block allocation scheme.
Communication to the patch is only enabled through custom-built
mobile applications. All MC10 applications require an authorized user
login using valid credentials. During operation, each patch is uniquely
assigned to a subject, in a specified configuration mode which includes
the sensor modality and body location. Patch to mobile and mobile
to patch communication is secured through a custom cmd-ctrl-data
protocol and compression algorithm that runs across the Bluetooth LE
protocol packets.
Mobile to MC10 Cloud Communication
Application data is encrypted (256-bit AES) and stored on the local
SQLite database on the mobile.
Upon network connectivity, data is transmitted between the mobile and
cloud using HTTPS protocols, which requires authentication with valid
credentials. This encrypted connection protects the privacy and
integrity of the exchanged data.
All cloud API interactions are logged with the following attributes:
•
Authenticated user taking the action
•
Source IP address of user
•
Time of interaction
•
Resources viewed or action taken
MC10’s cloud network and systems are protected with standard security
practices (firewalls, VPC, access restrictions, and automated
configuration management). Access to the data is restricted at multiple
levels and is protected by MC10’s Access Control Lists (ACLs) framework.
ACLs restrict resource availability to approved users and groups. Each
user belongs to at least one group and is assigned one or more roles
within their respective group. Roles define which resources and what
actions are available to a user in a given group.
Hazardous Situations
Potential hazardous situations resulting from a failure of the IT-NETWORK to
provide the characteristics required to meet the purpose of the PEMS
connection to the IT-NETWORK:
•
Investigator Portal, Investigator App, and/or Link App cannot connect to
public internet;
55

Erroneous data transfer between Investigator Portal, Investigator App,
and/or Link App and MC10 Cloud;
Data corruption on MC10 Cloud due to foreseeable misuse (i.e. hacking);
Investigator App or Link App can’t configure/control BioStamp Sensor;
Link Hub cannot control/download BioStamp Sensor;
Erroneous data transfer between BioStamp Sensor and Link Hub;
Link App cannot control/download smart charger;
Erroneous data transfer between Link App and Link Hub;
Data corruption on smart charger due to foreseeable misuse (i.e. hacking).
Connection of the system to an IT-network that includes other equipment
could result in previously unidentified risks to patients, operators, or third
parties. The responsible organization should identify, analyze, evaluate and
control these risks. Subsequent changes to the IT-network could introduce
new risks and require additional analysis. Changes to the IT-network include:
•
•
•
•
•
56
changes in the IT-network configuration;
connection of additional items to the IT-network;
disconnecting items from the IT-network;
update of equipment connected to the IT-network;
upgrade of equipment connected to the IT-network.
