Impedance Characterisation of Wearable Capacitive Sensors

on 18.08.2021 at 08:14 by Tim Ashworth
This blog post explains how the MFIA can be used to characterise wearable capacitive sensors and introduces two recent published studies where innovative flexible wearable sensors have been developed which operate on the principle of capacitive sensing. Both of these […]

DLTS User Meeting 2021 Q&A

on 19.07.2021 at 06:05 by Tim Ashworth
Deep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of semiconductor defects by measuring capacitance transients at different temperatures. As such, it is a critical tool for the characterization of […]

Low-Frequency DLTS of Perovskite Solar Cells with the MFIA

on 29.06.2021 at 00:19 by Tim Ashworth
Deep level transient spectroscopy (DLTS) is a powerful and commonly used technique to investigate the concentration and carrier binding energy of defects in semiconductors. The technique involves measuring capacitance transients at different temperatures, typically at 1 MHz. However, DLTS can also […]

Impedance Measurements with Small Amplitude Test Signals

on 03.06.2021 at 19:17 by Tim Ashworth
When taking an impedance measurement, the test signal amplitude can often be a factor which needs to be minimised to avoid unnecessarily disturbing the sample under test. This blog post presents measurements showing how even small test signals of just […]

Customising the Output Data Format of Impedance Sweeps

on 16.04.2021 at 12:05 by Tim Ashworth
This short blog post will show you how to customise the exported data of your impedance sweeps on the MFIA and MFLI with MF-IA option. The Sweeper Module of LabOne is an excellent tool to sweep frequency, amplitude or bias […]

Fast Frequency Sweeps for Impedance Measurements

on 19.01.2021 at 10:59 by Tim Ashworth
When characterising a device or material as a function of frequency, the resulting spectrum may change with time as the environment or material itself evolves. This time evolution can be captured by taking sequential frequency sweeps with the LabOne Sweeper […]

Compensating Cables for Accurate Impedance Measurements

on 19.01.2021 at 10:45 by Tim Ashworth
Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly […]

Inductance of an SMD Shunt Resistor measured with the MFIA

on 15.09.2020 at 10:32 by Tim Ashworth
The reliable and accurate measurement of current is critical to optimising any electronic system. The most commonly used method to measure current flows within a circuit is by using a low-value resistor mounted in series, and then measuring the voltage […]

Webinar Q&A- Impedance Analysis; Measuring Fast and Low

on 23.06.2020 at 08:01 by Tim Ashworth
This blog post answers the many welcome questions from the audience during the recent webinar “Impedance Analysis; Measuring Fast and Low”. This webinar covered two distinct and equally important impedance measurement challenges. The first involves measuring the low equivalent series […]

DC I-V Sweeps on the MFIA

on 10.01.2020 at 09:07 by Tim Ashworth
Characterizing the impedance of components and materials with the MFIA is done by necessity with an AC signal. However, the MFIA and MFLI can also take DC measurements. This blog post shows how easy it is to take DC measurements, […]
