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. […]

Function Generation Via Auxiliary Outputs on Your Instruments

on November 26, 2020 at 5:33 pm by Meng
Introduction Quite often one wants to generate an electrical waveform to assist his/her lock-in or impedance measurements. Such a function can be generated by a dedicated function generator, but ideally should be done in the same instrument, not only to […]

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 […]

Multiplexed Impedance Measurements with the MFIA

Electrochemical Impedance Spectroscopy of Tap Water with the MFIA

on January 6, 2020 at 6:09 pm by Meng
Introduction Electrochemical impedance spectroscopy (EIS) is a popular non-destructive technique to characterize the physicochemical properties of materials, particularly at the solid-liquid (or electrode-electrolyte) interface. Despite the complexity of the measured data, EIS can be used to study many electrochemical devices […]
