Abstract
Tactile sensors for wearable applications, e.g., electronic skins, robotic manipulators, etc., often require multi-modal sensing ability that enables combinations of pressure, shear, and bending stress/strain measurements. Carbon nanomaterials (CNMs) and CNM-derived polymer composites offer a high degree of freedom for sensor design and performance tunability. This paper presents recent studies on CNM-based, multi-modal tactile sensors, namely: (1) pressure-shear multi-modal sensor based on carbon nanocomposite pillar arrays; (2) multi-layered, micro-patterned nanocomposite pressure sensor with modulus gradient for wide-range sensitivity; and (3) bio-inspired, carbon nanotube(CNT)-coated hexagonal micro-columnar arrays with interlocking structure for pressure, shear and bending sensing.
