EITWatch open-source ESP32-S3 smartwatch implements planar EIT hand gesture recognition

Researchers from Northwestern University have introduced EITWatch, an open-source ESP32-S3-based EIT (Electrical Impedance Tomography) gesture-sensing system that fits within a standard smartwatch footprint. It relies on a Seeed Studio XIAO ESP32-S3 board and eight electrodes arranged on the back of the case to detect hand gestures via impedance changes caused by muscle and tendon movement beneath the skin. Unlike other wrist-EIT systems that use circumferential electrode bands, EITWatch places all eight electrodes on the back of the smartwatch case. The…
