Design of a Smart Glove Based on Flexible Printed Circuit Board

In this study, we designed a smart glove for measuring finger joint angles using a flexible circuit board. The glove design involves attaching a flexible printed circuit board with copper foil stickers applied to the joints of the fingers. On the back of the hand, a similar design using a flexible printed circuit board includes sleeves and coils. As the fingers bend, the copper foil pieces inside the sleeves slide, and the changes in coil impedance are measured to determine finger joint angles. Currently, the prototype smart glove has successfully calculated the angles of two joints in the right middle finger, achieving a resolution of 2° and a sampling frequency of 830 Hz.
