Q. Scientists have developed a soft, flexible and stretchable keyboard using a type of rubber known as a ____________ that can be wrapped around any object.- Published on 01 Dec 15a. Dielectric elastomer
b. Unilectric elastomer
c. Trilectric elastomer
d. Quadrilectric elastomer
ANSWER: Dielectric elastomer
This keyboard utilised the benefits of rubber devices that flex and stretch. Keyboard was made from a single laminated structure with two sensing layers oriented at 90 degrees apart utilising mechanical coupling while at the same time still provided an electrical separation. A total of 9 different positions were distinguished within the sensor keyboard.
