Tactile sensor, method of manufacturing, method of detecting, and flexible skin
By designing a stacked structure of four electrode units and a piezoresistive detection unit in the tactile sensor, the resistance change is decoupled, solving the problem that existing sensors cannot detect shear force. This enables simultaneous detection of normal force and shear force, expanding the applicability and improving detection accuracy.

AI Technical Summary
Existing planar piezoresistive tactile sensors can only detect normal forces and cannot effectively detect shear forces parallel to the contact surface, resulting in limited functionality and application range.
Design a tactile sensor that uses a first substrate layer, an electrode layer and a piezoresistive layer stacked together. The electrode layer includes an electrode unit with four individual electrodes. The piezoresistive layer is bonded to the individual electrodes to form four piezoresistive detection units. Normal force and shear force data are determined by decoupling resistance changes.
This technology enables the simultaneous detection of normal and shear force data, expanding the sensor's applicability and improving detection accuracy and sensitivity.
