In article number 2010962, Yuanjie Su, Guangzhong Xie, Jun Chen, and co-workers disperse polydopamine into barium titanate/polyvinylidene fluoride nanofibers to enhance the interfacial adhesion, mechanical strength, piezoelectric properties, creatively mimicking muscle fibers. The enhancement was theoretically verified via phase-field simulation. A nonwoven textile further fabricated for wearab...
