Advances in stretchable and flexible sensors are responding to the emerging demand of wearable and portable smart electronics. A core component of these electronics are tactile sensing devices which detect external stimuli and obtain in-time information from the surroundings. A fusion of electronics, physics and materials science, tactile sensors have great potential in robots, biomedicine, flexible interactive devices, and several other applications. By integrating with a flexible polymer matrix conductive materials (nanometals, carbon nanomaterials, conducting polymers, etc.), which are either embedded in the matrix or surface-coated or sandwiched between films, the resulting conductive polymer-based composites are promising for flexible tactile sensors. This review summarizes recent advances across different types of tactile sensors, including piezoresistive, capacitive, piezoelectric, and triboelectric. Examples …
