    • A pressure sensor having a digital output includes a substrate formed with plural channels, and a gating part formed in such a way that an area confronting with the plural channels is spaced from the substrate and moved in response to an external pressure, thereby making the plural channels selectively conductive. Such a pressure sensor can obtain binary information of each channel from the fact that which is made to be conductive among the plural channels is determined by the movement of the area formed in the gating part to confront with the plural channels, and it is possible to measure a pressure within a set range from binary information of each of the plural channels. As a result, because a peripheral circuit of the pressure sensor can be simplified, the manufacturing costs and power consumption can be greatly reduced.
    • 具有数字输出的压力传感器包括形成有多个通道的基板,以及形成为使得与多个通道相对的区域与基板间隔开并且响应于外部压力而移动的门控部件,从而使多个 通道选择性导电。 这样的压力传感器可以从由多个通道中形成的导电性的事实确定通过在门控部中形成的区域与多个通道相对的事实来确定每个通道的二进制信息,并且可以 从多个通道中的每一个的二进制信息测量设定范围内的压力。 结果,由于可以简化压力传感器的外围电路,因此可以大大降低制造成本和功耗。

    • A tire pressure monitoring system (TPMS) having a self-powered sensing module having a sensor unit with at least one sensor for measuring at least one of a temperature, a pressure, and an acceleration in the tire, and a power unit generating a power by being deformed mechanically according to a rotation of the tire and supplying the sensor with a power required for actuating the sensor. The self-powered sensing module and the TPMS using the same are powered by the power unit generating the power owing to the mechanical deformation, without using a separate power supply. Hence, there is no need to replace a battery of the sensing module and maintenance costs are reduced.
    • 一种具有自供电感测模块的轮胎压力监测系统(TPMS),其具有传感器单元,所述传感器单元具有用于测量轮胎中的温度,压力和加速度中的至少一个的至少一个传感器,以及产生功率的功率单元 通过根据轮胎的旋转机械地变形并且向传感器提供用于致动传感器所需的功率。 自供电的感测模块和使用它的TPMS由功率单元供电,由于机械变形而产生电力,而不使用单独的电源。 因此,不需要更换感测模块的电池,并且降低了维护成本。
