MobiEMG-WL is a mobile system designed to record signals like skin surface EMG, forces, pressures,... Thanks to its light weigth and its belt clip, it can be easily carried even by a young child. Up to 16 sensors dispatched on 8 push/pull connectors can be used simultanously. The signals are digitized and transmitted by Bluetooth in real time, thus allowing a computer, with appropriate software, to display the data in the same time. The important action radius (>100m) allows to use MobiEMG-WL in a wide range applications, from indoor clinical experiments to outdoor experiments in the sport field. The integrated memory card (512 Mo miniSD) allows also to use MobiEMG-WL like an autonomous recorder of long duration.

Two models of surface EMG amplified sensors are proposed. The first (BS-EMGP1) require Ag/AgCl stud electrodes with solid gel and the second (BS-EMGG1) integrates Gereonics miniature Ag/AgCl electrodes (11 mm in diameter with 2,5mm active part) which suit particularly to the recording of EMG signals produced by small muscles (arm, childs).
