elastomer

The artificial muscles, called actuators, are made by alternating ultrathin layers of elastomer and carbon nanotube electrode material and then rolling the stack of layers into a squishy cylinder.

Embedded in the elastomer are magnetically charged-particles.

ReSkin has an elastomer surface which is rubbery and bounces back when you press on it.

In the case of the covid detector, freeze-dried components that react with the virus are embedded in a paper mask, surrounded by a ring of silicone elastomer so the sample can’t evaporate or diffuse away from the sensor.

The same rubbery elastomer is sometimes used in shoe soles and car tires.

The bullets come out of the elastomer sleeve for further cleaning and battery replacement.
