Nanogenerators Getting Easier and Cheaper to Make, Presaging Explosion of Self-Powered Nanomachines:
Now researchers at the Korea Advanced Institute of Science and Technology (KAIST) have taken up the mantle of Wang’s work by creating a piezoelectric “nanogenerator” more easily and cheaply than ever before.
The research, which was initially published in the Wiley journal Advanced Materials, produced a piezoelectric nanocomposite through relatively simple processes such as spin-casting and the bar-coating method. So this new generation of “nanogenerators” is not restricted by a complicated and high-cost process or even size.
Even Wang himself is impressed by this work. “This exciting result first introduces a nanocomposite material into the self-powered energy system, and therefore it can expand the feasibility of nanogenerator in consumer electronics, ubiquitous sensor networks, and wearable clothes,” says Wang.
