Piezoelectric effect used by US researchers to develop a wearable device that could generate energy from swing of an arm while walking or jogging
The US researchers have developed a wearable device that could generate energy from the swing of an arm while walking or jogging. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system. The prototype watch is apparently made from a crystal material, which can produce an electric ..
Harvard scientists have created the world’s smallest radio receiver out of diamond imperfections called nitrogen-vacancy (NV) centres. The NV centers are capable of emitting single photons or detect very weak magnetic fields. When the NV centers receive radio waves it will convert them and emit the audio signal as red light. A common photodiode will convert ..
