Elastic components played several important roles in pressure sensors,such as accommodating deformation,resilience,and piezo electricity variation.However,the performance of many pressure sensors is limited by the bulk mechanical properties of the elastomer,such as large modulus,creep and viscoelasticity.We present a new material design concept to impart elasticity to a rigid conducting polymer by forming hollow-sphere nanostructures,and a new type of piezoresistive sensor which is highly sensitive due to the structure-induced-elasticity of the active layer thereafter [1].
