Electroadhesion Heralds New Implant And Robot Tech

Applying electricity for a few seconds to a soft material, such as a slice of raw tomato or chicken, can strongly bond it to a hard object, such as a graphite slab, without any tape or glue, a new study finds. This unexpected effect is also reversible—switching the direction of the electric current often easily separates the materials, scientists at the University of Maryland say. Potential applications for such “electroadhesion,” which can even work underwater, may include imp
