Abstract

Elastomers are emerging as an alternative to inorganic materials for electromechanical transducers. The rubber-like polymers are characterized by high elasticity (their equivalent elastic modulus is typically 2 orders of magnitude lower than that of silicon) and high yield strain (>;100%). They offer a unique opportunity to design and fabricate transducers, which can then shape complex, three-dimensional structures and accommodate moving structures. This paper reports on the design and technology to manufacture stretchable mechanical sensors and demonstrate an ultra-compliant 3×3 touch sensor matrix.
