Increasing technical demand for organic user interface(UI), which is intuitive interaction with electric devices, causes growth of research interest for a flexible sensor. Considering device applications, which use electrical control, it is desired to convert mechanical deformation of flexible devices into an electrical signal such as current against deformation stress. As an approach to this desire, we introduce novel and simple structures of a passive and active stretchable sensor by using soft materials and electrode compounds. As a result, we study enhanced capacitance variable sensor up to 21.8% against uniaxial stretching stress up to 40%. In further, we also report an active type stretchable sensor with a modified thin film transistor structure manipulating electroactive material, which can convert energies between mechanical deformation and electrical polarization change. In this study, detailed results and sensing mechanisms in either passive and active ways will be discussed. |
