Engineers at the Fraunhofer Institute for Ceramic Technologies and Systems in Germany have come up with an improved wireless system from which to transmit power to medical implants or drug dispensers. InnovationNewsDaily reports that the device is designed to power implants, medical dosing systems and even pill camera capsules that are swallowed and take pictures as they travel through the gastrointestinal tract. It works through the use of magnetic coupling, which delivers power from about 20 inches away--a wider range than existing systems. Plans call for demonstrating the technology at the Hannover Messe tech trade show in Germany from April 23 to April 27. Story
