Nanogenerator-based dual-functional and self-powered thin patch loudspeaker or microphone for flexible electronics
Abstract
Self-powered nanogenerators by harvesting energy from the environment are desirable for future portable and wearable electronics. Liet al. show the use of ferroelectret nanogenerators to build microphone or loudspeaker, which convert electrical signals to mechanical motions in a reversible manner.
