Summary:Electronic skin (e-skin) technology with high sensor distribution and versatility is required to develop robotic systems that exhibit the characteristics of living organisms. However, the scaling up of e-skins results in, issues such as the need for increased wiring, long readout time, and high power consumption. This study introduces a new circuit for a serial sensor network inspired by the signal propagation of neurons. The network comprises many sensor nodes chained together, wherein each node comprises only four logic elements for fast sub-microsecond readout and low power consumption (microwatts). Similar to neurons, each sensor node communicates only with the adjacent node, thereby avoiding an increase in the bus line load or a reduction in the communication bandwidth during scaling up. Additionally, various sensor products can be installed in a general-purpose manner.
