Abstract: Stretchable electronics have great potential for applications in unconventional electronics. The wrinkling of a stiff thin film on a compliant substrate is of particular interest to achieve this aim. The desired mechanical properties are realized not through new materials but instead through new structural configurations of existing materials. In this study, the fabrication procedure of stretchable silicon systems is carried out. Controlled buckling is realized in single crystal silicon thin films and integrated circuits. Both linear and nonlinear analytical study is performed to find a closed form solution. Critical buckling strain is obtained and the wavelength and amplitude are predicted for the buckling and post-buckling phases. The numerical analysis is carried out using FEM. The simulation results exhibit good agreement with experimental observation and show this stiff thin film-compliant substrate system has good stretchability and compressibility. There are many exciting research possibilities and a correspondingly bright future in this area.
