Tactile sensation plays a crucial role in human interaction with the environment,
facilitating the perception of various physical stimuli such as pressure,
texture and temperature through the skin. Mimicking human tactile perception,
the development of flexible tactile sensors has seen significant growth,
significantly expanding their applicability in robotics, medical devices and
wearable technology. This paper reviews recent advances in flexible tactile
sensor technology, with a focus on the development of multifunctional sensors
capable of detecting multiple types of tactile stimuli simultaneously. Unlike
traditional rigid sensors, flexible tactile sensors integrate the sensitivity
and elasticity of human skin, enabling them to adapt to different surfaces and
detect a wider range of stimuli.
