Special Issue on Universal Power Supply Technologies for Era of Trillion Sensors
Guest Editor: Keiji Takeuchi (NTT Data Institute of Management Consulting, Inc.)
A gyroscopic power generator that generates a power of 1.8 W is developed with a rotor of 100 mm diameter and 500 rpm spin speed. In conventional vibration generators, which use simple vibration ... Read More
Piezoelectric energy harvesters are expected to power trillions of miniaturized sensors. We theoretically analyze nanogenerators with aligned piezoelectric nanorods using formulaic solutions and ... Read More
This study focuses on the notch effect on FeCo/Ni clad plate cantilevers. We investigated the response of the cantilevers to an external load and the energy conversion performance. The three-po ... Read More
In this paper, we present a high-speed battery charger, powered by a photovoltaic (PV) module array, for a LiFePO4 battery as a solar energy storage device. With a battery charging strategy, the ... Read More
Assuming that a wireless sensor is installed to determine the state of facilities along a railway, we verified the possibility of applying environmental energy as a power source for the sensor. ... Read More
