Smart garments for monitoring physiological and biomechanical signals of the human body are key sensors for personalized healthcare. However, they typically require bulky battery packs or have to be plugged into an electric plug in order to operate. Thus, a smart shirt that can extract energy from human body motions to run body-worn healthcare sensors is(More)
Self-powered human-interactive but invisible electronics have many applications in anti-theft and anti-fake systems for human society. In this work, for the first time, we demonstrate a transparent paper-based, self-powered, and human-interactive flexible system. The system is based on an electrostatic induction mechanism with no extra power system(More)
Aligned fibrous scaffolds have attracted much interest in bone tissue engineering, because they are supposed to induce osteogenic differentiation. For the first time, aligned silk fibroin nanofibres were loosely packed using a novel wet-collection electrospinning method. Moreover, three-dimensional (3D) culture of MC3T3-E1 pre-osteoblasts was established on(More)
