1. The ACES architecture for large arrays with single-wire transmission capability.
The ACES architecture for large arrays with single-wire transmission capability. Illustration of ACES artificial receptors on e-skin (left) that independently and asynchronously transduce tactile events into pulse signatures, analogous to biological action potentials, or spikes (right). (A) ACES receptors generate tactile events with spatiotemporal structures (dashed lines) that encode the stimulation sequence. (B) Pulse signatures are combined and propagated via a single conductor. (C) Decoders match pulses in time. A strong match with correlation |T| exceeding a predefined decoder threshold (shaded box) indicates the presence of an event by the particular receptor. The decoded events preserve the spatiotemporal structure (dashed lines) of receptor activation with ultra-high temporal precision, resembling the spike patterns that enable rapid discrimination in the somatosensory system.
