Researchers at Oxford University have developed a tiny battery that can power small implantable devices, such as drug delivery technologies. The new battery is inspired by the ionic gradients that electric eels use to generate electricity. It involves tiny droplets of a conductive hydrogel that are placed near each other. Each droplet has a different ionic concentration, meaning that ions will flow from high concentration droplets to low concentration droplets. When the researchers connect electrodes to this chain of droplets they can harness the energy generated by this ion gradient in th
