Self-powered enzyme micropumps
Nature Chemistry, 2014Non-mechanical nano- and microscale pumps that function without the aid of an external power source and provide precise control over the flow rate in response to specific signals are needed for the development of new autonomous nano- and microscale systems.

The harvesting of mechanical energy from ambient sources could power electrical devices without the need for batteries. However, although the efficiency and durability of harvesting materials such as piezoelectric nanowires have steadily improved, the voltage and power produced by a single nanowire are insufficient for real devices.

Self-powered wireless energy meter
Proceedings of the 1st International Workshop on Energy Neutral Sensing Systems, 2013We 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.

This article explores nanotech machines and says they need a better power source than batteries. The creation of nanogenerators makes power on a tiny scale that may permit the use of waste energy in the form of vibration or the human pulse to power devices. Piezoelectric nanowires could capture the energy to run nanodevices.

Cognitive Radio With Self-Power Recycling
IEEE Transactions on Vehicular Technology, 2017In 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, 2014A 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), 2017Nowadays, 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 ...
