Wearable flexible touch sensor of artificial hand and touch detection system thereof

The invention discloses a wearable flexible touch sensor of an artificial hand and a touch detection system thereof. A flexible electrode layer, a middle layer and a PDMS (Polymethylsiloxane) raised layer are tightly laminated from top to bottom; the middle layer comprises a conductive rubber array and a flexible filler around the conductive rubber array; the conductive rubber array is formed by configuring conductive rubber unit arrays; a testing electrode assembly is arranged below the conductive rubber array; the side length of the conductive rubber unit is the same with that of the testing electrode assembly on the flexible electrode layer; a micro lug boss structures are arranged on the PDMS raised layer which is located above the conductive rubber units; the flexible electrode layer is a flexible circuit board with a crossed structure; Velcro nylon fastener tapes are arranged at the extending edges of the upper side, the left side and the right side of the flexible circuit board so as to be worn on a finger. The wearable flexible touch sensor is simple and easy to manufacture, solves a problem of major touch sensors incapable of simultaneously detecting three-dimensional touch force and slippage signals and can be conveniently bound on the irregular curve of a support body inside artificial fingers.
