摘      要：Self-powerability is a new trend in the development of portable *** biomechanical energy to power personal information electronics is of great *** this work,we report a wearable noncontact freerotating hybrid nanogenerator(WRG),which is constituted by a triboelectric nanogenerator and an electromagnetic generator.A continuous output over 2 seconds can be achieved during one instantaneous incentive by external force,which is improved by two orders of magnitude compared to other wearable nanogenerators due to its unique mechanical energy storage *** WRG can be integrated into shoes to generate an output energy of 14.68 mJ in each stepping,which meets the power requirements of most personal information *** wireless sensor,GPS,and smartphone can be powered by the WRG *** WRG is expected to be applied in self-powered information electronics extensively in the future.
