High-power electrostatic actuators to realize artificial muscles

Electrostatic actuators are simple and lightweight devices that emulate human muscles. However, their usage has primarily been restricted to moving small devices since they need high voltages to generate significant forces. ...

Nanostructured ceramic coatings do not fatigue, finds study

Extremely thin ceramic coatings can completely change the properties of technical components. Coatings are used, for example, to increase the resistance of metals to heat or corrosion. Coating processes play a role for large ...

New strategy to effectively prevent component failures in metals

When a metal is stressed far below its yield strength at elevated temperatures, a process known as creep can occur. Creep, the time-dependent deformation of materials, is responsible for a great number of component failures ...
