Dust-Sized Sensors Could Create “Electroceuticals”

University of California, Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles, or organs in real time. These batteryless sensors, called neural dust, can also be used to stimulate nerves and muscles, opening the door to “electroceuticals” to treat disorders such as epilepsy, stimulate the immune system, or tamp down inflammation.
