Body temperature can also be sent to the Institute of electrical energy technology

Institute of research and development for many years, by using the waste heat energy into electrical energy, "hunting technology", from the large to 300 degrees below the heat plant, small to rub your hands can "turn through the thermoelectric control chip can become available power application system, a program of environmental protection and energy saving.

In Kaohsiung two Art District, P2 barge warehouse, often see a group of people listened, rub palms Fagong, trying to use the temperature generating energy, light light made by OLED column. This is the hunting technology sponsored "decryption technology ITRI treasure" on the "".

The Institute said, will hand rub on the wafer to the LED lights, the temperature is higher, the LED lamp is bright, the principle of this technique is the use of a thermoelectric energy conversion module, the module is composed of thermoelectric conversion module and thermoelectric materials can form a control chip, through the power control turn the chip with low voltage and high current electrical power into usable application system, with the thermoelectric material module is, the higher the power.

The Institute pointed out that in the energy collection chip, also the most important collocation of maximum power tracking calculation function, through the output voltage detection, the thermoelectric conversion efficiency of the real-time control in the optimal operating point, the maximum output power, output power to achieve the best.

At the same time in the design of energy collection chip, in order to avoid power consumption of the chip itself is too large, the exhausted power at the same time, the development of the most simple circuit to achieve complex functions, and the characteristics of low power consumption, the world's smallest chip reached.

The Institute says, "hunting can turn ultra low voltage chip can collect waste heat energy utilization technology, not only can be used in flashlights and laser pen carry to replace the battery, the charging power supply can also be made into smart wearable device; steam locomotive exhaust pipe temperature is very high, with a thermoelectric wafer to collect waste heat into the the electric energy, reduce fuel consumption and reduce emissions; the larger is the heat generated by the machine factory or stove operation, especially in 300 degrees Celsius heat is difficult to recover, with hunting technology into electrical energy for lighting factory.

In addition, the "hunting technology" even under normal temperature small temperature difference can also generate electricity, for example temperature using human skin and the environment to generate electricity, a substantial increase in the range of heat thermoelectric power generation "and the possibility of only a small amount of electricity, also can transform and use.

The Institute for example, is not easy to achieve power in outdoor environment, can play a key effect to hunting technology ". For example, the use of physiological monitoring device in motion on the one hand through the body heat into electricity, but also can drive the device to detect heart rate, blood pressure and other physiological conditions, in order to achieve record, alarm and communication etc..

Below 120 degrees Celsius on the work table can also be applied to hunt technology, equipped with a sensor device to monitor the equipment to avoid damage and affect production capacity, to reduce greenhouse effect, improve the environment is also very helpful.
