Solar Power driver: wearable devices automatically regulate body temperature, leading a new trend in health

The human body can only withstand so much heat or cold. This can be a problem in extreme environments, from polar temperatures below zero to the scorching heat of the Sahara Desert, and it's not just limited to Earth. Maintaining temperature is also a problem for astronauts. The vacuum in space is a huge freezer; exposed to direct sunlight can be as cruel as cold.

The clothing technique for regulating body temperature usually has only one way: heating or cooling. It is also often bulky and requires a lot of energy, ultimately depleting any battery. What if there is a system that can both heat and cool while using a constant amount of renewable energy?

A group of researchers led by Ziyuan Wang from Nankai University in Tianjin, China, have created a flexible solar device that can be integrated into clothing and regulate the body by actively heating or cooling the skin. It can also work continuously for 24 hours and be charged with sunlight.

Wang's new system combines the power of solar cells with the energy of card devices. Solar cells, called photovoltaic cells, consist of semiconductor materials that can absorb energy from sunlight and convert it into electrical energy. In this case, the photovoltaic material used is a flexible polymer. Another component is the electric heating device, which changes temperature when placed in an electric field. Applying a magnetic field heats the material while removing the electric field cools the material.

Any energy stored during the day becomes particularly useful after the sun sets. In the darkness, the system will automatically retrieve energy from the storage attachment to continue running throughout the night. The heating and cooling modes can be easily switched when heating or cooling. Moreover, when the system runs out of energy, there is no need to insert anything – it can be charged after being exposed to direct sunlight for 12 hours.

Solar Power is a technology that converts solar energy into electrical energy. This technology exploits solar panels to convert solar energy into a continuous current, which is then converted into alternating current through an inverter. Solar Power, as a renewable, clean, and environmentally friendly energy source, has a wide range of application areas:

1. Photovoltaic power generation: Using the photovoltaic effect, solar energy is converted into direct current energy, which is then supplied to the load or battery storage.

2. Heating and hot water: Solar water heaters use solar energy to heat additive water for household or industrial purposes.

3. Agricultural irrigation: Using solar-powered water pumps to provide irrigation water for farmland.

4. Greenhouse: By installing solar panels at the top of the greenhouse, solar energy provides the necessary light and heat for plant growth.

5. Lighting and Landscape: Solar street and landscape lights use solar panels to collect energy and release light at night or on cloudy days.

6. Communication and control: Solar energy provides power and supports remote communication and control operation.

7. Navigation aids and signal lights: Solar-powered navigation aids and signal lights provide navigation and warning information in remote areas.

8. Spacecraft: Solar energy provides satellites and space probes continuous energy.

9. Electric vehicle charging: Using solar energy to provide electricity for electric vehicle charging stations.

10. Building Energy Efficiency: Integrating solar energy technology for building heating, cooling, and power supply systems.
