Piezoelectric materials vs. SMA Piezoelectric materials are crystalline materials that generate a voltage at the both ends when pressure is applied to them to deform the surface; the most important characteristic is the piezoelectric effect, including the piezoelectric effect and the inverse piezoelectric effect. Piezoelectric effect refers to the application of a force to the piezoelectric material for deforming the surface of the piezoelectric material, thus forming charges at both ends of the...(more)
As shown in the fig1pictures below, there are little few appearance differences between TEC and TEG, but their principles and applications are not the same. Fig 1. The photo of TEC and TEG Based on semiconductor materials, a thermoelectric cooler (TEC) can be used as an electronic component of a small heat pump. Through by adding a little low DC voltage to both ends of TEC, heat quantity will flow from one end to the other, and at the same time, the temperature of one end will decrease and the o...(more)
The common specifications voltage of LED lights are 12V and 24V, and one team of 12V LED light consists of three pcs LEDs, while24VLED light is made up of six pcs LEDs. Once, some customer requested to reduce the power supply voltage, but h...(more)
TEC modules (thermal electric cooler), also called Peltier modules, can cool down or heat up the object when changing the current direction. The current is DC current. There are some advantages and disadvantages of TEC module. Advantages: A. No cryogen needed. TEC modules can work constantly for hours. It contains no pollution or rotating components, which results no noise and vibration, long life span and easy installation. B. Very short heating-up and cooling time due to small thermal lag in T...(more)
NTC thermistor can be applied in many fields, such as temperature measurement and control, temperature compensation, surge current suppression, environmental measurement, etc. There are some common failures and causes for NTC thermistor 1. Short circuit: When theloop current is higher than Imax, or power rating is higher than Pmax for a long time, it will make the temperature of the thermistor higher than Tmax. At the start, the thermistor will have a rather low resistance, and then the thermist...(more)
