Microscale soft-robots hold great promise as safe handlers of delicate micro-objects but their wider adoption requires micro-actuators with greater efficiency and ease-of-fabrication. Here we present an elastomeric microtube-based pneumatic actuator that can be extended into a microrobotic tentacle. We establish a new, direct peeling-based technique for building long and thin, highly deformable...

Microelectromechanical systems (MEMS) devices have been increasing in popularity for radio frequency (RF) and microwave communication systems due to the ability of MEMS devices to improve the performance of these circuits and systems. This interdisciplinary field combines the aspects of lithographic fabrication, mechanics, materials science, and RF/microwave circuit technology to produce moving...

We report the successful fabrication of a micro-pseudocapacitor based on ternary nickel cobalt sulfide for the first time, with performance substantially exceeding that of previously reported micro-pseudocapacitors based on binary sulfides. The CoNi2S4 micro-pseudocapacitor exhibits a maximum energy density of 18.7 mW h cm(-3) at a power density of 1163 mW cm(-3), and opens up an avenue for exp...

A technique for electron multiplication in gas is being developed that lends itself to easy fabrication with lithographic techniques. Moreover, the electrical characteristics of the resulting device are very stable. Comprising an array of anode pins that are recessed into a closely-packed hexagonal cathode, the MIcro-Pin Array (MIPA) represents a promising addition to micro-pattern detectors wi...
