"MEMS: Radioactive isotopes fuel microscopic battery "
Cornell professor Amit Lal uses radioactive isotopes as fuel for a tiny battery developed that could turn out to be an ideal power source for remote sensors or other small-scale systems. Microelectromechanical-systems (MEMS) technology creates a millimeter-size battery that can run for decades. The research team plans to scale the prototype to even smaller dimensions so that it could become a power source for MEMS sensors.
