Proximity sensors: inductive or capacitive? Using the MFIA to measure the sensitivity and response time of both sensing regimes

on January 7, 2021 at 5:36 pm by Meng
Introduction A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. […]

Measuring Dielectric Properties of Materials with Varying Thickness

on September 30, 2020 at 8:52 am by Meng
Introduction A dielectric is traditionally defined as an electrical insulator, with very poor conductivity at DC [1]. However, because of its polarizability, charges can be stored in a dielectric material, typically in the format of dipoles, in the low and […]

Humidity Sensors: Resistive or Capacitive? The MFIA can tell the Answer.

on June 15, 2020 at 3:31 pm by Meng
Introduction Humidity sensors (also known as hygrometers) are commonly used in applications ranging from everyday sensing to lab research [1]. They are typically placed in an enclosed chamber, such as a car or a glovebox, where they are used to […]
