Low cost, large area, ultra-sensitive, flexible sensors are important for variety of engineering.

Applications: electronic skin, intelligent textiles, smart switches and devices for autonomous manipulation of objects, energy harvesting, stress measurement, vibration control and so on. Such sensors will be using soft rubbery films with their surface and bulk patterned with nano-microscopic features like hairs, pillars, islands and pyramids. The effective material properties of these films will be strong function of the dimension of these features. Therefore, any change in loading on the film surface will alter their modulus, dielectric constant, capacitance and others which will be measured
