Semiconductor chiller, also called thermoelectric chiller, is a type of heat pump. It has the advantage of no sliding parts, used in some space constraints, high reliability requirements, no refrigerant contamination. Using the Peltier effect (second hot spot effect) of semiconductor materials, when the DC current passes through the electric couple formed by two different semiconductor materials in series, the two ends of the electric couple can respectively absorb heat and release heat, which can achieve the purpose of refrigeration. It is a negative thermal resistance of the refrigeration technology, its characteristics are no moving parts, and relatively high reliability.

On September 4, 1882, Edison became the first to light the J.P. Morgan Building on Wall Street after nearly a decade of research. A few years later, eccentric inventor Nikola Tesla patented alternating current (AC) transmission, making it possible to transmit electricity over long distances. Hence the grid, which carries electricity from power plants to blocks, buildings and homes thousands of kilometers away.

Ceramic antenna is a kind of miniaturized antenna. The material of the antenna is ceramic shell, which has the ability of anti-interference, anti-lightning, waterproof and dust-proof. Its weight is only 200g, and the reading distance can reach 2 meters. Because of its relatively close reading distance, it is also known as the short-range antenna. The frequency range is generally between 902MHz and 928MHz. It is a very suitable antenna for Bluetooth devices.
