Piezoelectric Glove Design and Test for Future Wearable Devices

We present the first results of experimental measurements performed to estimate the available energy derived from the movement of the fingers of one hand. The proposed system consists of a mechanical hand made with a 3D printer, on which 5 piezoelectric strips are applied, electrically connected in series or in parallel. Measurements have shown that the series configuration produces the best result. In this configuration, in fact, the open circuit peak-to-peak voltage reaches 39.6V.
