Wearables Design Kit
This wearable smart patch is part of a kit designed to facilitate the experimentation and accelerate the development of artificial intelligence-based health diagnostic devices, from wrist watches, clothing, bracelets, neckless, VR helmets to miniature smart rings.
The sensor patch makes available an extensive set of physiological measurements and it is complemented by an SDK and the SLM-Studio multi-sensors data logging and AI framework, running on most PCs. All measurements are performed by a single SENSIPLUS analog front-end chip which assures coordinated and timed data acquisition for sensor fusion.
The 16 electrodes matrix allow to intermix bio-impedance, bio-potential and electrochemical measurements in support of low resolution imaging. Multiple patches can be daisy chained and operated concurrently to enable large area body measurements.
