3D printed piezoelectric BNNTs nanocomposites with tunable interface and microarchitectures for self-powered conformal sensors

3D printing of arbitrary shapes and unique architectures offers unparalleled flexibility and simplicity for fabrication of highly complex 3D conformal electronics. It drives up high demands in electronic materials with excellent processability and functionality simultaneously. Herein, we overcome this challenge in prepared nanofiller/polymer piezoelectric composite by incorporating ultralow loadings (0.2 wt%) of boron nitride nanotubes (BNNTs)...
