A highly sensitive tactile sensor is devised by applying microstructured graphene arrays as sensitive layers. The combination of graphene and anisotropic microstructures endows this sensor with an ultra-high sensitivity of –5.53 kPa−1, an ultra-fast response time of only 0.2 ms, as well as good reli...
