An insect-scale soft robot has fast relative speed of motion, high load-carrying capability, and exceptional robustness.
- Microwheels on microroads: Enhanced translation on topographic surfaces
Matching textured surfaces to microwheel sizes and symmetries may lead to more efficient propulsion of microdevices.
- Biomimetic sensory feedback through peripheral nerve stimulation improves dexterous use of a bionic hand
Sensory feedback improves dexterous use of a bionic arm, and sensory signals that mimic natural ones are more intuitive and useful.
- A microrobotic system guided by photoacoustic computed tomography for targeted navigation in intestines in vivo
An imaging-guided ingestible microrobotic system enables deep tissue navigation and enhances targeted retention in vivo.
- A neuro-inspired artificial peripheral nervous system for scalable electronic skins
A scalable communication architecture enables asynchronous readout of thousands of tactile sensors through a single conductor.
- Long-term implant of intramuscular sensors and nerve transfers for wireless control of robotic arms in above-elbow amputees
The use of implantable myoelectric sensors showed substantial improvements in prosthetic function of above-elbow amputees.
About The Cover
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.
