Recently, many devices have appeared that use the thermoelectric effect to generate electricity. Its essence is to convert the temperature difference into electrical voltage. One of the main problems of these devices remains the use of elements harmful to humans – cadmium, tellurium and mercury.
Scientists from the University of Utah created a thermoelectric material, where there are no toxic chemical compounds. It uses a combination of perfectly safe for human calcium, cobalt and terbium.
The new material will find application in various fields. Medical implants can be powered by jewelry, which generates electricity due to the difference between body temperature and ambient air.
Cars and airplanes will be able to use the difference between the heat inside the cabin and the outside cold. And even from kitchen pans and pans made of new material, you can recharge mobile phones. A huge potential is located in thermal power plants , wasting up to 60% of energy.
The team has already received the first applications for material from automakers and manufacturers of biosensors.
