Self-powered wireless energy meter

Proceedings of the 1st International Workshop on Energy Neutral Sensing Systems, 2013
We present the design of a Wireless Electrical Energy Metering node (WEM) for the integration in a wireless sensor network. The node has energy harvesting capability for long lasting monitoring, and measures the power consumption, of residential and industrial appliances, in the range 10W--10kW.

Cognitive Radio With Self-Power Recycling

IEEE Transactions on Vehicular Technology, 2017
In cognitive radio networks, a secondary user (SU) equipped with radio frequency (RF) energy-harvesting circuits can not only harvest the RF energy from the primary transmitter, but also recycle its self-power when transmitting. In this paper, we are concerned with the following design metrics: SU's harvested energy, SU's energy efficiency, and SU's ...

Self-Powered Glucose-Responsive Micropumps

ACS Nano, 2014
A self-powered polymeric micropump based on boronate chemistry is described. The pump is triggered by the presence of glucose in ambient conditions and induces convective fluid flows, with pumping velocity proportional to the glucose concentration. The pumping is due to buoyancy convection that originates from reaction-associated heat flux, as verified

Smart-shoe self-powered by walking

2017 IEEE 14th International Conference on Wearable and Implantable Body Sensor Networks (BSN), 2017
Nowadays, electronic devices are more and more compact and can be integrated in nearly every object. One of the remaining challenges is to provide smarter ways to power those electronic devices. Because of the small amount of energy needed by the latest ultra-low power systems, energy harvesting from the environment becomes a viable solution to power ...

Self-powered lightning current sensor

2016 IEEE SENSORS, 2016
In this paper, a self-powered lightning current sensor based on the electromagnetic induction principle has been proposed. The sensor whose signal coil and power harvesting coil are nested in lightning channel (such as grounding wire of lightning arresters) can be triggered and powered by the lighting current.
