Sensors Expo & Conference 2018: Calibrated Sensor Simplifies In Vivo Pressure Measurements

Silicon Microstructures’ next generation of the IntraSense product line embarks as a fully temperature compensated and pressure calibrated version that simplifies setup and use. The company says it’s the first commercially available pressure sensor that fits into 1-French tubes and has pre-attached wires for ease of integration. With a calibration board now available on the proximal end of the device, setup and readout are even easier, with both amplified analog as well as digital outputs attached to a 5-pin connector.


The extremely small size of the sensor allows it to be attached to catheters, endoscopes and other equipment where space is at a premium. In addition to established pressure measurement procedures in cardiology and neurology, IntraSense allows equipment designers to add pressure-sensing functionality to new applications in urology, ENT, reproductive health, guided biopsies and other disciplines.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.


Calibration and subsequent submersion in saline ensures stable performance (<1 mmHg change in output in 37°C saline) for at least twelve hours. The sensors are calibrated across a pressure range from -300 mmHg to +1300 mmHg, and from 0°C to 101°C. Users may use amplified analog outputs or an optional standard I2C digital interface for easy system integration.


You can get even deeper insights by attending Sensors Expo & Conference 2018, and visiting SMI in booth #1121. Until then, to whet your appetite for knowledge and keep your anxiety in abeyance, check out the IntraSense datasheets.
