Molecular ferroelectrics are promising for human interfaced high frequency acoustic sensing, though existing ferroelectric materials are often brittle making them impractical for sensors. Here the authors describe a stretchable ferroelectric material, using trimethylchloromethyl ammonium cadmium chloride and polyurethane electrospun for high-accuracy speech recognition under stretching.
