Tactile e-skin is a flexible sensor array designed to mimic the human sense of touch. It consists of thin, polymer-based membranes embedded with conductive grids that can detect changes in pressure and shear force.
Tactile e-skin addresses the need for advanced haptic feedback in robotics, prosthetics, and wearable devices to improve interaction with the environment.
The technology works by using capacitive or piezoresistive sensing arrays. These arrays map out the distribution of pressure and shear across a surface, allowing for precise tactile feedback.
The manufacturing process involves depositing conductive materials onto flexible polymer substrates. This is followed by patterning and layer stacking to create the sensing arrays.
Initial development stages involve material selection and deposition techniques such as spin coating or inkjet printing. Further steps include patterning, bonding, and encapsulation for protection.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking.
