The device will be used for continuous monitoring of basic vital signs such as pulse, blood saturation, body temperature, and electrical activity of the heart.
A traditional ECG test takes several minutes and is performed in a lying position.
This makes it rare to detect irregularities that occur every day during ordinary activity.
Thanks to continuous monitoring of vital parameters around the clock, it is possible to record a full picture of the heart's activity in "natural conditions": during rest, activity, work, sports, eating meals, etc.
The prototype version of the device will consist of nRF9151 DK and a board with Arduino standard connectors containing an analog front-end (AFE) for recording electrical biopotentials, an accelerometer, connectors for connecting a thermometer and a saturation and pulse sensor, e.g. MAX30100 or MAX30102 Heart-Rate Oximeter Pulse Sensor.
The ADS1298 is an 8-Channel 24-bit simultaneous sampling delta-sigma analog-to-digital converters with built-in programmable gain amplifiers, internal reference, and an onboard oscillator.
The ADS1298 incorporates all of the features that are commonly required in medical electrocardiogram (ECG) and electroencephalogram applications.
The LSM6DS3TR-C featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 0.90 mA in high-performance mode will be used to measure user activity.
Data collected during device operation can be sent via the LTE-M/NB-IoT network thanks to the nRF9151 modem. The GNSS receiver will allow the patient's location to be determined.
When access via the NB-IoT or LTE network is not possible, the device will connect wirelessly via WiFi to a mobile device such as a smartphone or tablet and use tethering to communicate with remote server.
Data pre-processed by the device's processor can then be analyzed by the doctor or automatically by AI on the server.
The device will consist of:
- nRF9151 DK or Arduino Giga R1 WiFi
- ADS1298 Analog Front End
- MAX30100 or MAX30102 Heart-Rate Oximeter Pulse Sensor
- LSM6DS3 iNEMO sensor - 3D digital accelerometer and a 3D digital gyroscope
- Battery
