Abstract: Capturing respiration signal using a microelectromechanical (MEMS) accelerometer is a challenging task. The design of the interface circuit of the sensor must consider the characteristics of ...

Innovative conductive hydrogel mimics living tissue, enabling oxygen sensing and electrical control of growth factors, paving ...

What if a small sensor could understand space in three dimensions? A maker recently showed how a Time-of-Flight (ToF) sensor can be turned into a basic 3D scanner. The sensor sends out infrared light ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Abstract: Radiation sensor interface circuits can be mounted on sensor nodes in wireless sensor networks to detect radiation signals. They respond quickly to operators and command centers, allowing ...

An improved passive wireless sensor is presented for ultra-high temperature environments, utilizing a folded Complementary Split-Ring Resonator (CSRR) structure. A dedicated back-end circuit ...

I live in New Jersey, one of the states that mandates inspection for all vehicles newer than 1995. My daily driver, a Jeep Cherokee, happens to be a 1996 model year with an OBD-II sensor, meaning I ...

There are many different trouble codes that can be set in the system when there’s an issue with an oxygen sensor. One such example is the P0133 code. What does it mean and how does it differ from ...

We earn commissions from purchases you make using links in our articles. Learn more. If your car experiences poor fuel economy, lacks power, feels sluggish, idles rough, or has an illuminated check ...

Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that ...
