Tag Archives: Energy scavenging

We are chemical factories, our bodies is continuously engaged in metabolic processes and these produce heat (we are dissipating this heat through breathing and, unique in the animal world, through sweating). When we are packed in a closed environment we act like heeeating devices and the room temperature goes up. …

We live in a world of energy, continuously fuelled by the Sun (and, in a minimal part, by radioactive decade). Energy as such is no good. What is needed is to transform one form of energy into another one. We use gasoline (chemically stored energy) and by combining it with …

To capture energy you don’t need “energy”, what you need is a difference in “energy” between two points so that you can transfer energy from one point (that we defined as having more energy) to the other (that we define having less energy). The concept of energy seems quite straightforward …

I saw a number of research in the past trying to scavenge power energy in the ambient, including the one produced by living being. It is nothing really new! As a matter of fact the very first “experiments” in electricity were the ones of Luigi Galvani who shocked the world …

A team of researchers at UC San Diego University have announced the development of a sophisticated sensor placed on a stretchy material (elastomer) that is able to generate ultrasound aiming them under the surface of the object (might be a knuckle as in the image or a neck or a …

One of the crucial issues in many IoTs is how to power them in ways that they can harvest data and transmit them to a receiver connected to the Internet. Actually the most difficult part is to power the (wireless) transmission because that is where most power is required. Local …
