Semiconductor Strain Gauge Structure Diagram Circuit
The semiconductor strain gauge is mainly produced by using the piezoresistive effect of the silicon material. If there is the force on the semiconductor crystal, the crystal would have the strain effect and also its electric resistivity would change. This phenomenon of the electric resistivity's change of the semiconductor material caused by the external force is called the piezoresistive effect of the semiconductor. The semiconductor strain gauge is completed directly by a series of technics processes of cutting, grinding, cutting, welding wire, pasting etc. on the semiconductor material such as single crystal germanium or single crystal silicon. Its structure is shown in the picture. The picture shows the semiconductor strain gauge structure diagram circuit.   (View)

Blood Pressure Sensor Circuit
As shown in the picture, this circuit uses BP01 type pressure sensor and operational amplifier MAX4472. The BP01 type pressure sensor is specially designed for blood pressure which is mainly used in portable electronic blood pressure meter. It uses the precise thick-film ceramic chip and nylon plastic package and it features high linearity, low noise and small external stress. Also it uses internal standard and temperature compensation method to improve the measuring accuracy, stability and repeatability. In its full measuring range the accuracy is ±1%, the zero point distortion would not be more than ±300μV. The MAX4472 is a MAXIM company's low-power amplifier chip with four integrated operational amplifiers.   (View)
