A brainwave-monitoring headset powered by body heat and sunlight has been created at the in Belgium. A thermoelectric material turns the temperature difference between a warm head and the surrounding air into electricity. Two small solar panels also provide power. The headset could monitor patients for seizures or be used to control computer games by thought alone.
