Subproject A03
Highly Integrated Localizable Wireless EMG Transponder
Sub-project A03 aims to develop the EmpkinS Beacon (EB), a miniaturized, flexible, and energy-efficient wireless radio transponder for monitoring muscle activity using surface electromyography (sEMG) and tracking body movement. It combines innovative sensor technology with advanced radio transmission and localization for medical applications such as Parkinson’s monitoring and emotion detection. The EB integrates multiple sEMG channels on a flexible substrate, fuses data with motion sensors, and features a precise localization system for comprehensive movement analysis. Two concepts are being investigated that allow simultaneous data transmission and localization of the EB: sEMG with a discrete 24 GHz RF transmitter and sEMG with a highly integrated 61 GHz RF transceiver for miniaturization and accuracy. Full integration of the EB on flexible substrates is also being explored.
