If you answered 120 over 80 mmHg, you are using criteria that is over 20 years old. As reported in a 2003 article, revised guidelines categorized normal blood pressure as <120/80 mmHg. Since the measurements are meant to lower the risks from not recognizing what is often called the silent killer – high blood pressure […]

Pressure sensors for medical application offer fast response time
Superior Sensor Technology announced two new CP Series pressure sensors for Positive Airway Pressure (PAP) devices used in sleep apnea, COPD, Asthma, and home ventilator applications. Based on Superior Sensor’s highly integrated CP Series dual pressure sensor architecture, the new CP202 and CP302 closed-loop control functionality and overpressure indicator enable manufacturers to easily upgrade their PAP […]
How is sensing involved in deep sea exploration?
As the recent loss of OceanGate’s Titan tourist vessel has revealed, exploring in the ocean’s depths is very risky business. To see the Titanic up close and personal, the Titan would have to travel to a depth of 3,800 m (12,467 ft), where the pressure is 382.45 bar (5,547.14 psi or 38,246.06 kPa). It turns […]
Waterproof pressure sensor provides digital memory and connunications
STMicroelectronics has introduced the market’s first MEMS water/liquid-proof absolute pressure sensor with a declared 10-year longevity program for the industrial market. ST’s new ILPS28QSW sensor comes in a sealed, cylindrical, surface-mountable package. It features a ceramic substrate that provides high resistance to liquid permeability and a robust potting gel, proven in automotive applications, to protect the […]
When to use sound pressure and when to use sound intensity measurements
Sound pressure, sound intensity, and sound power are three different ways to quantify sound. This FAQ begins by defining each one, looks at various types of measurement techniques that can be used to quantify them, presents a range of international testing standards for measuring sound, looks at instruments used for measuring sound pressure and intensity, […]
BLE for TPMS addresses smarter, connector vehicle tires
Sensata Technologies announced it has developed a new Bluetooth Low Energy (BLE) Tire Pressure Monitoring System (TPMS) for vehicle OEMs to help improve vehicle safety and performance. Interest in BLE TPMS is on the rise as vehicles become more connected, electrified, and autonomous. While common in consumer applications like speakers and headphones, BLE is […]
Ultra-low-noise barometric pressure sensors target smart home appliance apps
TDK Corporation announces that the InvenSense ICP-20100, the latest generation of the SmartPressure MEMS Barometric Pressure Sensors, is now in mass production and has been certified by NextNav. Launched in 2021, the NextNav Certified process independently verifies the InvenSense sensor accuracy measurements, by engaging directly with component manufacturers to rigorously test sensors in real-world operating […]
Barometric pressure sensor targets mobile device apps
Bosch Sensortec introduces the BMP581, a barometric pressure sensor that couples low power consumption with extreme accuracy to provide altitude tracking in wearables, hearables, or IoT devices. This capability makes it ideal for applications such as fitness tracking, fall detection, indoor localization, and navigation, enabling new use cases that were previously impossible. This extreme level […]
What sensors does NASA use to monitor Martian weather?
The Mars Environmental Dynamics Analyzer (MEDA) on the Perseverance rover is characterizing the surface weather as well as the dust particle size and morphology. Understanding dust behavior is a key to predicting Martian weather. Dust influences Mars’ weather the way that water controls Earth’s weather. Two of MEDA’s weather-related goals are: determination of the destructive […]
