ONLINE COVER ACES Architecture. Electronic skins (e-skins) can facilitate robotic interactions with objects and environments, but equipping e-skins with enough sensors for precise and rapid data processing has been difficult. Lee et al. developed the Asynchronously Coded Electronic Skin (ACES) system, which mimics biological action potentials and mechanoreceptors to transmit thermotactile information from sensors in e-skin to a single conductor without complex wiring or signaling delays. ACES detected heat and pressure with high temporal resolution, even across dozens of sensors; was not susceptible to background electromagnetic interference; and continued to operate after mechanical damage to the e-skin.
