Thermoelectric devices may have an essential role in the development of fuel-saving, environmentallyfriendly, and cost-effective energy sources for power generation based on direct conversion heat into electrical energy. A wide usage thermoelectric systems already exhibits high reliability long operation time space industry gas pipe systems. The application solar generators (TEGs) arelimited ma...

In this paper, we present a real and simulated study of frequency up mixing employing an electro-optical sampling semiconductor optical amplifier Mach–Zehnder interferometer (SOA–MZI) along with the differential modulation schema. The signal is generated by pulse clock (OPC) at fs= 19.5 GHz. quadratic phase shift keying (QPSK) intermediate (IF) fIF shifted to high frequencies nfs ± SOA–MZI outp...

IC A IO N We have been working on “self-powered nanotechnology” since 2005 with the aim to build self-powered systems that operate independently, sustainably, and wirelessly without the use of a battery. [ 1 , 2 ] One of the great applications for such a self-powered system is that it can be used for driving portable/wearable personal electronics in our daily life. Nanogenerators (NG) are one o...

This paper presents an optimization of the voltage doubler stages in an energy conversion module for Radio Frequency (RF) energy harvesting system at 900 MHz band. The function of the energy conversion module is to convert the (RF) signals into direct-current (DC) voltage at the given frequency band to power the low power devices/circuits. The design is based on the Villard voltage doubler circ...
