Electrically tunable ionic hydrogels use small voltages to switch friction at metal contacts between high-friction and ...

Analog cameras are nowhere near as efficient as biological eyes. If you’ve ever handled a single-lens reflex (SLR) camera, especially if it had a zoom lens attached, you know how heavy they are, and ...

YouTuber [MechnicalRedPanda] has recreated a DIY STM hack we covered about ten years ago, updating it to be primarily 3D-printed, using modern electronics, making it much more accessible to many folks ...

Abstract: This paper presents the actuator with adjustable stiffness (AwAS-II), an enhanced version of the original realization AwAS. This new variable stiffness actuator significantly differs from ...

Abstract: Soft actuators typically exhibit low stiffness and low load-bearing properties due to the intrinsic limitations of soft materials. Stiffness modulation is an effective means to improve the ...
