From the project
Discrete validation platform for the HEEPidermis low-power SoC, designed for low-noise Galvanic Skin Response (GSR) measurements
The GSR Monitor Board is designed as a validation platform for the HEEPidermis SoC, currently under development at the Embedded Systems Laboratory (ESL), EPFL. This board facilitates testing and evaluation of key functionalities, particularly focusing on high-precision Galvanic Skin Response (GSR) measurement with low noise operation.
