Helper scripts and shell for measuring **T**ribo**e**lectric **N**ano**g**enerator-based sensor output with a Keithley 2600B SMU or an Arduino
|
|
|
|
This project was written for my bachelor's thesis.
|
|
|
|
## Features
|
|
|
|
### Interactive (shell) mode
|
|
- Live view
|
|
- Press button to stop
|
|
- Save and load settings (default interval, data directory...)
|
|
- Easily run arbitrary command on device
|
|
|
|
|
|
### Useful functions for scripts
|
|
- Measure voltage and/or current
|
|
- Transfer buffer from measurement device to host
|
|
- Save/load as csv
|
|
- Run lua script on Keithley SMU
|
|
- Auto-filenames
|
|
|
|
|
|
## Available backends
|
|
### keithley
|
|
Use a Keithley 2600B Source-Measure-Unit via *pyvisa*. This backend allows measuring both voltage and current simultaneously. *Tested with 2611B and 2614B*
|
|
|
|
### arduino
|
|
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).
|
|
|
|
### testing
|
|
Use the shell without measuring TENG output. When starting a measurement, sample data will be generated.
|
|
|
|
|
|
## Shell mode
|
|
It is recommended to run the shell with ipython:
|
|
```shell
|
|
ipython -i k_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
|
|
|
|
|
|
## Installation
|
|
### Keithley
|
|
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`.
