As a result of the PHIDIAS project, a new wearable educational demonstrator has been prepared. The Inyu-PHIDIAS CS demonstrator is able to acquire a 1-lead ECG signal by simple touch of two fingers on a planar embedded system including a new low-power microcontroller, memory and (at least) two metal contacts. This demonstrator can be used for educational purposes at university or high-school to show the use of applying different compressive sensing (CS) ratios to the original ECG signal in real time. The Inyu device can be purchases through Smartcardia, a Swiss start-up based in Lausanne. For more information about the device and ordering details, please visit www.smartcardia.com
