Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. There are two main forms: the piston actuators and diaphragm actuators. Piston actuators are ...

Hydraulic rotary actuators use a pressurized, incompressible fluid to rotate mechanical components. They are faster and more powerful than pneumatic actuators because the high pressures used in ...

In order for a VR environment to seem real, it definitely helps if you can experience the sensation of touch within that virtual world. A special sleeve could soon allow people to better do so, using ...

Stanford researchers introduce a soft flexible sleeve offering pressure-based touch feedback, redefining virtual reality and communication interfaces.
