Helper scripts and shell for measuring Triboelectric Nanogenerator-based sensor output with a Keithley 2600B SMU or an Arduino
This project was written for my bachelor's thesis.
- Live view
- Press button to stop
- Save and load settings (default interval, data directory...)
- Easily run arbitrary command on device
- Measure voltage and/or current
- Transfer buffer from measurement device to host
- Save/load as csv
- Run lua script on Keithley SMU
- Auto-filenames
Use a Keithley 2600B Source-Measure-Unit via pyvisa. This backend allows measuring both voltage and current simultaneously. Tested with 2611B and 2614B
Use a Bluetooth capable Arduino with [https://git.quintern.xyz/MatthiasQuintern/teng-arduino](this software on the arduino). This backend only allows measuring voltage using an Arduinos analog input pin (0 - 3.3 V, 12 bit resolution).
Use the shell without measuring TENG output. When starting a measurement, sample data will be generated.
It is recommended to run the shell with ipython:
ipython -i m_teng_interactive.py -- -*X*Substitute X for -k for keithley backend, -a for arduino backend or -t for testing backend.
In the shell, run help() to get a list of available commands
On linux:
Install the udev rule in /etc/udev/rules.d/ and run sudo udevadm control --reload to force the usbtmc driver to be used with the Keithley SMU.
The ATTRS{product_id} needs to match the id shown by lsusb.
