Skin Stretch Display

A type of haptic display technology that produces tactile feedback by laterally stretching the skin of the user's fingertip, rather than using raised pins or vibration. Skin stretch displays typically use arrays of small actuators (such as piezoelectric bending motors) that deflect to create patterns of lateral skin deformation, enabling users to perceive different textures, shapes, and boundaries through touch. This technology has been applied in accessibility contexts to create refreshable tactile graphics for people with visual impairments, offering advantages over traditional pin-based displays including finer resolution and the ability to render continuous textures like dots, waves, and vibrations.
