In this paper, we report a novel graphene-based nanogenerator for high energy harvesting. Experimental and theoretical results revealed that the energy output mechanism is the joint action of the strain effect (band engineering) and the triboelectric effect of reduced graphene oxide. It was found that the current could be adjusted by experimental parameters, such as the electrolyte concentratio...

Harvesting unexploited energy in the living environment to power small electronic devices and systems is attracting increasing massive attention. [ 1–7 ] As the size of the devices has shrunk to the nanoor microscale, the power consumption also decreased to a modest level, i.e., the microwatts to milliwatts range. It is entirely possible to drive such a device by directly scavenging energy from...

Biomedical electric devices provide great assistance for health and life quality. However, their maintainable need remains a serious issue the restricted duration of energy storage. Therefore, scientists are investigating alternative technologies such as nanogenerators that could harvest mechanical human heart to act main source pacemaker. Cardiac contraction is not circulation; it utilizes bod...

A simple fabrication route for ion gel nanofibers in a triboelectric nanogenerator was demonstrated. Using an electrospinning technique, we could fabricate a large-area ion gel nanofiber mat. The triboelectric nanogenerator was demonstrated by employing an ion gel nanofiber and the device exhibited an output power of 0.37 mW and good stability under continuous operation.

Sensors have recently gathered significant attention owing to the rapid growth of Internet Things (IoT) technology for real-time monitoring surroundings and human activities. Particularly, discovered nanogenerator-based self-powered sensors are potential candidates overcome existing problems conventional sensors, including regular monitoring, lifetime a power unit, portability. Halide perovskit...
