Energy Harvesting Using Nanowires?

Energy Harvesting Using Piezoelectric Nanowires-A Correspondence on "Energy Harvesting Using Nanowires?" by Alexe et al

We have demonstrated an innovative approach to convert mechanical energy into electrical energy by piezoelectric zinc oxide nanowire (NW) arrays. The mechanism of the nanogenerator (NG) relies on the coupling of piezoelectric and semiconducting dual properties of ZnO as well as the elegant rectifying function of the Schottky barrier formed between the metal tip and the NW. Alexe et al. have rec...

Energy harvesting performance of piezoelectric ceramic and polymer nanowires.

Energy harvesting from ubiquitous ambient vibrations is attractive for autonomous small-power applications and thus considerable research is focused on piezoelectric materials as they permit direct inter-conversion of mechanical and electrical energy. Nanogenerators (NGs) based on piezoelectric nanowires are particularly attractive due to their sensitivity to small-scale vibrations and may poss...

Using Activated Transport in Parallel Nanowires for Energy Harvesting and Hot Spot Cooling

We study arrays of parallel doped semiconductor nanowires in a temperature range where the electrons propagate through the nanowires by phonon-assisted hops between localized states. By solving the random-resistor-network problem, we compute the thermopower S, the electrical conductance G, and the electronic thermal conductance Ke of the device. We investigate how those quantities depend on the...

Thermal Energy Harvesting Using Fluorinated Terpolymers

Energy Harvesting Communications Using Dual Alternating Batteries

We consider an energy harvesting transmitter equipped with two batteries having finite storage capacities, communicating over an additive white Gaussian channel. The work is motivated by an observation that many practical batteries, when repeatedly charged after being partially discharged, suffer from degradation in the usable capacity. The capacity can be recovered by completely discharging th...
