Tactile switches (a specific type of momentary switch) are everywhere and they are especially popular on DIY electronics and microcontroller boards because they are well suited to act as a boot option or reset switch. Particularly, momentary switches are switches that don’t save their state when you depress the switch. That is, when you push the switch (and while you have the switch depressed) the circuit is ON, but once you let off the switch it reverts back to OFF.

New Tactile Sensor Is Lighter Than A Feather
Many researchers are focusing on flexible electronics, but the ones coming out of Someya-Sekitani Lab are the thinnest and most flexible circuits to date, the researchers say. (They have aptly nicknamed their work “imperceptible electronics.”) The sensors can conform to almost any 3-D shape. They’re also resilient, the research team says: the sensors maintain functionality up to 170 degrees C (though beyond 100 degrees C their efficiency gradually tapers off); they’re nearly unaffected when immersed in saline solutions; and they can be crumpled up, flattened back out, and even placed on rubber and stretched out–none of which drastically impacts performance.

Researchers at the École Polytechnique Fédérale du Lausanne (EPFL) have developed a technique for giving touchscreens tactile surfaces, so that users have the impression of touching a raised surface. Among the many potential applications, it could be used to make touchscreens more accessible for people with visual impairments.
The novel technique, developed by EPFL’s Integrated Actuators Laboratory in Neuchâtel, is targeted at smartphones, tablets, computers, and vending machines. [via]
