Fig. 3: The firing rates of the neuromorphic tactile signals.

The distribution of the spiking rate of the neuromorphic tactile signals computed over the 6 by 6 tactile sensing elements. The horizontal axis stands for the locations of tactile sensing elements within the contact area, the vertical axis is the spiking rate. a The spiking rate of the neuromorphic tactile signal elicited under cylindrical and spherical grasping for SAI. b The spiking rate of the neuromorphic tactile signal elicited under spherical grasping for FAI.
