Wearable technology requires high-performance sensors with properties such as small size, flexibility, and wireless communication. Stretchability, sensitivity, and tunability are crucial sensor properties; stretchability and sensitivity ensure user comfort and accurate sensing performance, while tunability is essential for implementing sensors in diverse applications with different ranges of motion. In this study, we developed fast responsive strain sensor with the help of PVDF/TPU. In this experiment we developed rapid synthesis polymer based photonic crystal. Those crystals are monodisperse spheres and easy a boiling temperature soap-free emulsion polymerization was developed. A number of polymer and copolymer spheres with a size of several hundreds of nanometer were synthesized. Comparing with the conventional synthesis, this method has following advantages: (1) the experimental set-up and operation are simplified, (2) the reaction time is shortened, (3) ease of control of sphere size and size distribution with good repeatability.
