 This video presents a wearable biosensing system for hand gesture recognition. The flexible electrode array is printed with conductive silver ink on PET substrate. Here you can see the screen printing process and the resulting array of 64 electrodes. We apply a drop of conductive hydrogel on each electrode to improve the electrode skin impedance. The array is then wrapped around the forearm. The user is instructed to perform each gesture only once to train the insensor classifier. Here we show the real-time inference of gestures as well as the system in action controlling robots and a prosthetic arm.
