Transducers 101: Test Your Knowledge of Energy Conversion Devices

NASA Marshall Space Flight Center developed designs for two micro-electromechanical systems (MEMS) motion and position sensors: a single-axis accelerometer and a gyroscope. The designs leverage a highly aligned multi-wall carbon nanotube (MWCNT) tape with a P(VDF-TrFE) matrix that is mechanically ro

Modern engines rely on a network of sensors and an Engine Control Unit (ECU) to deliver optimal fuel efficiency and performance. Among these, the Manifold Absolute Pressure (MAP) sensor plays a pivotal role in monitoring engine load and guiding fuel metering decisions. What Is a MAP Sensor? The MAP

Inside every cellphone is a tiny mechanical heart, beating several billion times a second. These micromechanical resonators play an essential role in cellphone communication. Buffeted by the cacophony of radio frequencies in the airwaves, these resonators select just the right frequencies for transm

Learn the fundamentals of magnetometers, how they measure magnetic fields, and their wide-ranging applications—from everyday electronics to deep-space probes. Magnetometers are precision instruments that quantify either the magnitude or direction of a magnetic field. They are ubiquitous in modern e
