Tiny robots and sensors need tiny batteries — here’s how to do it

Compact batteries, such as lithium-ion ones, are produced using wet chemistry - painting slurries of materials on metal foils, for instance. Magnetic guiding can help: incorporating a tiny amount of ferromagnetic material into the battery film and applying a magnetic field can keep the curling proce...
