How about a wearable armband that can keep your body at the ideal temperature inside the house? That’s exactly what scientists at UC San Diego have created. It works inside for more than eight hours and can lower skin temperature by up to 10°C (50°F), making it a more viable solution when central heating and / or air conditioning is not available. How does it work? Well, is relies on thermoelectric alloys, which use electricity to create a temperature difference, placed between heat-conducting stretchy sheets and connected to a small battery pack.

“Tested on one person at background temperatures ranging from 22 to 36C (72 to 97F), it stayed at a constant 32C (90F). An electric current from the battery moves across the pillars, driving heat from one sheet to the other. If the heat goes to the sheet closest to someone’s skin, they warm up. If it is transferred to the sheet furthest away, warmth is removed from their skin and they cool down,” reports The Daily Mail.
