Body temperature can also generate electricity, Taiwan Institute of Technology, hunting technology, super environmental protection
ITRI ​​has been researching and developing for many years, and has completed the use of waste energy technology that converts waste heat into electrical energy. From large to 300 degrees of waste heat in the factory, small and hot hands can control the wafer to become the power available to the application system through the thermoelectric transfer. Pay attention to environmental protection and energy conservation. In the P2 warehouse of the Kaohsiung Barge Art Center, a group of people are often seen to concentrate on their work, trying to use the body temperature to generate electricity and light the energy column made of OLED lights. This is the hunting energy technology exhibited by the Decryption Technology Treasures sponsored by the Industrial Technology Research Institute. ITRI ​​said that the LED lamp can be lit by placing the palm of the hand on the wafer. The higher the body temperature, the brighter the LED lamp. The principle of this technology is to use a thermoelectric conversion module. This thermoelectric conversion module is The thermoelectric material module and the transducing control chip are formed, and the electric power of the low voltage and the large current is converted into the power available for the application system through the thermoelectric conversion control wafer. As the temperature difference of the material module is larger, the power generation power is increased. high. ITRI ​​pointed out that in this energy harvesting chip, it is also equipped with the most important maximum power tracking calculation function. By detecting the output voltage, the conversion efficiency of the thermoelectric power is immediately controlled at the optimal operating point to generate the maximum electric energy. , to achieve the best output power. At the same time, in the design of the energy harvesting chip, in order to avoid excessive power consumption of the chip itself, exhausting the generated power, while developing the simplest circuit to realize complex functions and low power consumption, the world's smallest wafer is achieved. volume. ITRI ​​said that Hunting Technology uses ultra-low voltage trans-power chips to collect waste heat energy, which can not only replace the battery used in portable flashlights and laser pointers, but also can be used as a charging power source on smart wearable devices; exhaust of steam locomotives The temperature of the tube is very high. It can also collect these waste heat into electric energy by using thermoelectric wafers to reduce fuel consumption and reduce exhaust gas emissions. The larger one is the heat generated when the factory machine or stove is running, especially the waste heat that is difficult to recover below 300 degrees Celsius. , using hunting energy technology into electrical energy for factory lighting. In addition, hunting energy technology can generate electricity even with a small temperature difference at normal temperature. For example, using the temperature difference between human skin and the environment to generate electricity, greatly increasing the range and possibility of thermal temperature difference power generation, only a small amount of electricity can be converted and utilized. For example, ITRI can play a key role in hunting energy technology in an environment where it is difficult to obtain electricity outdoors. For example, when used in a physiological monitoring device during exercise, on the one hand, the body's heat is converted into electric power, and at the same time, the device can be driven to detect physiological conditions such as heartbeat and blood pressure to achieve functions such as recording, warning, and communication. Hunting technology can also be applied to work machines below 120 degrees Celsius. It is equipped with a sensor device to monitor equipment to avoid damage and affect productivity. It is also helpful for reducing greenhouse effect and improving the environment.
