Live demonstration: A kilohertz kilotaxel tactile sensor array for investigating spatiotemporal features in neuromorphic touch

Spatiotemporal spike patterns from mechano-receptors enable rapid propagation and processing of tactile stimuli. To explore similar mechanisms in neuromorphic touch, tactile sensors of comparable scale and sampling rates are needed. In this demonstration, we present a 4096 element tactile sensor array that is capable of sampling rates of over 5kHz. We exhibit high speed capture of pressure changes and improved discrimination of contact parameters through increased dimensionality. Such a platform permits the development of time sensitive neuromorphic algorithms for tactile perception and signal processing.
