Abstract

This study proposes a piezoelectric polyvinylidene fluoride (PVDF) patch for detecting the movement of the biceps brachii muscle. The polyurethane (PU) elastomer was chosen to perform as an artificial muscle. The PVDF patch rigidly glued onto the stretching PU strip could generate the charge linearly with its applied force. The large strain of 1-4 % of the PU at a low driving voltage has led to the determination of the piezoelectric charge coefficient (d₃₁) of 30 pC/N for the PVDF. The sensing PVDF-PU patch in this study is promising for detecting the electromyography of the biceps brachii muscle movements which can be repeatable used with ease.
