The future of winter, you no longer have to wear like a rolling bear, but as long as a thin jacket, adjust to a comfortable temperature, you can go out.

At a recent meeting of the American Chemical Society, the US Army Natick Soldier Research said they are working on a technology that will allow for temperature regulation on normal fabrics and may eventually go into consumption market.

In extremely cold weather, the soldiers will wear as many as seven layers of clothes, which makes them feel heavy and have mobility problems. Inspired by Yi Cui, a researcher at Stanford University, researchers at the US Army Natick R & D Center have started to study the optimization of fine silver nanowire technology by coating fine silver nanowire coatings on ordinary fabrics such as cotton or polyester, Volt energy can generate a lot of heat. They are also developing a control system that allows soldiers to manually control the temperature.

Fine silver nanowire coating does not change the fabric flexibility, also passed the detergent test. Currently they have made gloves using the fine silver nanowire coated fabric that is optimized for application to clothing

"We found that if we connect the treated fabric to a battery or power supply, we can raise the fabric temperature to 110 degrees Celsius, which is a huge change," said D'Angelo, a researcher at the US Army Natick Center for R & D. Of course, soldiers do not need so much heat, but this shows the potential of the cloth to heat up with only three volts of electricity, and only three volt of watch battery.

However, the three volt power is the energy required to heat a 1 inch by 1 inch fabric, and if the entire package requires more power then the battery becomes a heavy burden. The research center is working with professors at the University of California, San Diego to develop a stretch-stretchable battery that can be incorporated into textiles with virtually no weight.

In fact, before the market has appeared a lot of clothes can be adjusted temperature. ClimaWare, created by MIT student Kranthi Vistakula, passes the Peltier effect (Peltier effect means that when a current flows through a loop of different conductors, in addition to producing irreversible heat, at different conductor junctions The current direction of the different will be respectively endothermic, exothermic), two metal connected to each other will be exothermic, one will endothermic. However, ClimaWare is too geeky in image, not suitable for ordinary people's everyday wear.
