How to measure current in TENG circuit

01 January 1970 1 3K Report

We have created a TENG, using PTFE ball and Aluminum electrode in vertical Contact separation mode. The output measured using a high precision Multimeter was 0.3 V. But when we tried to measure current by connecting a resistor in series, and by short circuiting, the output was zero. Can someone point out the problem behind this ?

As the cell voltage and currents are low, you can high end DC programmable electronic loads for measurements. It will measure mV and mA with very small loads
