Rice University electrical and computer engineering students are working on a design for a wireless pacemaker. The pacemaker consists of a base unit located under the patient's skin and a network of chips, each the size of a grain of rice. When the base unit senses a change in the patient's heart rhythm it signals the chip network to deliver a jolt of electricity to establish normal rhythm. Since there are no wires, the unit charges through radio frequency radiation similar to the technology used in RFID chips. Learn more about the wireless pacemaker at Rice University.
