Allegro MicroSystems has introduced the A17700, an automotive-grade interface IC for resistive bridge pressure sensors featuring signal conditioning algorithms.

Fig 4. Exposing the modified pressure sensor to laser energy created a temperature-induced change in the piezo-resistive element’s resistance that corresponded directly to laser power.

A tweak of the drive electronics for resistive tactile sensors lets these devices handle an expanded range of pressures.

The A17700 is configurable for resistive bridge pressure sensors in a wide range of critical applications in today’s efficiently designed cars; from high-pressure systems like dynamic brake ...

Approximately a third of patients suffer from patient-ventilator dyssynchrony during mechanical ventilation. Pressure sensors can be used to combat dyssynchrony through increased tailoring to the ...

Electronic skin displays human-like reactions to pressure, temperature and pain Another point in favour of the sensor is its resistance to friction: tests showed that it could be rubbed 300 times with ...

The piezo-resistive method: A resistive bridge circuit is formed by introducing impurities onto the surface of the diaphragm. When pressure is applied to this circuit, the resistance changes. By ...
