This blog summarizes the webinar that Fluigent and Zurich Instruments presented together our solution for fast electric impedance spectroscopy (EIS) in microfluidics. The system consisted of an HF2LI lock-in amplifier from Zurich Instruments and the LineUp series microfluidic flow controllers […]

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

on 07.01.2021 at 17:36 by Meng on Blog of Meng Li
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. […]

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

on 15.06.2020 at 15:31 by Meng on Blog of Meng Li
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 […]

Electrochemical Impedance Spectroscopy of Tap Water with the MFIA

on 06.01.2020 at 18:09 by Meng on Blog of Meng Li
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 […]
