Best For
Section titled “Best For”- Students and developers running a first sEMG or EMG experiment.
- Users comparing dry electrodes, wet electrodes, and onboard dry electrodes.
- Developers using Arduino, ESP32, STM32, oscilloscopes, or external ADCs.
- Small labs building gesture recognition, HCI, robotics, or low-cost biosignal prototypes.
Electrode Options
Section titled “Electrode Options”| Option | Notes |
|---|---|
| Lead-wire wet electrodes | Usually the easiest way to get the first stable waveform. |
| Lead-wire dry electrodes | Useful for repeated experiments without disposable gel electrodes. |
| Onboard dry electrodes | Useful for quick skin-contact tests and mechanical validation. |
What You Still Need
Section titled “What You Still Need”- An ADC, oscilloscope, or MCU acquisition device.
- Battery power or another low-noise isolated supply.
- Software for displaying, recording, or analyzing waveforms.
- Electrode leads and pads if you use external electrodes.
