When rain falls on a lotus leaf, the leaf doesn't get wet. Thanks to its special structure, the water drops roll off without wetting the surface. Artificial materials can be made water-repellent, too.

Stiction, the tendency of a control valve or actuator to stick in position until a threshold force is exceeded, represents a pervasive source of non-linearity in automated feedback systems. In process ...

Micro-electro-mechanical systems, popularly referred to as MEMS, in small electronic devices often fail because of adhesion and stiction - the attractive force between the surfaces of interacting ...

Generally, water repellent objects and those that attract or absorb water have very different microscopic-level attributes that endow them with their behavior. For example, the myriad tiny hairs on a ...

CES 2017 was the year of always-on voice: Alexa stole the show as the speech assistant that was seemingly everywhere. The sheer variety of Alexa-enabled products was overwhelming, with everything from ...

Stiction is a problem in nano- and micro-electromechanical systems (NEMS and MEMS) whereby the tiny components stick together, often greatly reducing the reliability and long-term durability of these ...

Demand for micro electro-mechanical systems (MEMS) technology is on the rise. To service that demand with reliable products, both developers and users of MEMS devices need to know about likely failure ...

A simple one-piece sleeve is sometimes better for reducing friction than complex rolling-element bearings. Besides being greaseless, journal bearings can be made out of high-tech plastics for weight ...

(Nanowerk News) Micro-electro-mechanical systems, popularly referred to as MEMS, in small electronic devices often fail because of adhesion and stiction - the attractive force between the surfaces of ...

Barcelona, Spain. Nanusens has announced that its CMOS nano-sensor technology has been successfully used to solve the problem of stiction in MEMS inertial sensors, which is a major source of failure ...

This engine is likewise wondrously free of stiction and internal inertia and is smoother than hot-buttered sin. "Rumble Seat: Less Is More in BMW's Complacently Excellent 3," Off Duty, March 3 ...
