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 ...

Boeing is now testing the new Remote Vision System 2.0 for the KC-46A's troubled telescoping boom system, which addresses serious Category 1 deficiencies. The Department of the Air Force announced on ...

By addressing both of those issues, Lightship hopes to make the trailer almost range neutral, allowing the tow vehicle to go nearly as far on a full battery or tank of gas as it would when not towing.

Optical telescopes utilize refraction and reflection to focus light, enabling detailed astronomical observations and ...

Multiple challenges are contributing to a depressed construction forecast for 2025 to 2026; there is, however, light at the ...

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 ...

Actuators are the input and output devices that connect electronic, hydraulic or pneumatic control systems to their environment. They convert external forces or conditions, such as temperature, into a ...

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: Theoretical studies suggest and experimental evidence confirms that maintaining and changing human joint stiffness by coactivated antagonistic muscles are metabolically expensive, even if ...
