Have you ever wanted a way to harvest energy from everyday objects? Scientists have developed a new type of nanogenerator that can do just that! Using a special putty made of limestone and a polyacrylamide gel, this nanogenerator can harvest energy from motions such as tapping, rubbing, and squeezing. This energy can then be used to power small electronic devices, such as sensors, LED lights, and more. The nanogenerator is the first of its kind that is able to harvest energy from everyday motions, making energy harvesting easier than ever before.
