1. Damage resilience of ACES architecture compared with a conventional row-column multiplexed array.
Damage resilience of ACES architecture compared with a conventional row-column multiplexed array. (A) Photographs show the array before (top left) and after damage (bottom left), where the stretchable polyurethane substrate embedded with ACES-SA receptors was cut at three different locations. The corresponding pressure distributions reconstructed from ACES receptor outputs are shown to the right of each image. (B) Schematic of signal propagation path on damaged substrate of ACES receptor array. (C) Photographs of the four-by-four multiplexed sensor array before and after being cut. The plots to the right of each photograph indicate the sensor readout corresponding to the physical state of the sensor. (D) Schematic representation of the multiplexed sensor array. Each sensor element is represented by a variable resistor. Dashed lines indicate traces affected by the damage.
