Scientists discover diamonds can generate electricity

SMRTR summary

Researchers at the University of Hong Kong have overturned a century-old assumption by discovering that ultrathin, flexible diamond membranes can generate electricity when bent. The electrical response comes from charge buildup at grain boundaries inside the membrane. This breakthrough could lead to diamond-based implantable medical devices and tiny self-powered sensors, giving diamond an active electrical role rather than just a structural one.
