[Wotian share] The difference between diffused silicon piezoresistive pressure sensor and sputtering film pressure sensor

From: Issued date 2020.03.04 Back

The previous article shared the difference between a diffused silicon piezoresistive pressure sensor and a ceramic piezoresistive pressure sensor. Today,, we will share the difference between a diffused silicon piezoresistive pressure sensor and a sputtering film

 

Material of sputtered film pressure sensor

[Wotian share] The difference between diffused silicon piezoresistive pressure sensor and sputtering film pressure sensor 

The sensitive sensor of the sputtered film uses the ion beam sputtering technology to directly bind the nano-film strain resistance and the metal elastomer directly on the ceramic insulating film, thereby achieving the atomic bonding of the metal elastomer and the insulating film.

 

Diffused silicon piezoresistive pressure sensor is made according to the principle of piezoresistive effect

Characteristics of Sputtered Film Pressure sensor

 [Wotian share] The difference between diffused silicon piezoresistive pressure sensor and sputtering film pressure sensor

With corrosion resistance, anti-vibration, wide measurement range, high measurement accuracy, etc.

 

Diffused silicon piezoresistive pressure sensor with high accuracy and small linearity

 

Price of Sputtered Film Pressure sensor

 

Because the rang2020-03-04 pressure sensor is relatively large and the process is complicated, the price is relatively expensive.

 

Diffused silicon piezoresistive pressure sensors are relatively affordable and cost-effective.
