# m-TENG
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

### 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.
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*
ipython -i m_teng_interactive.py -- -*X*
```
Substitute *X* for `-k` for keithley backend, `-a` for arduino backend or `-t` for testing backend.
