This is the openEMSstim, a hardware board based on an Arduino Nano that modulates the amplitude of Electrical Muscle Stimulation (EMS) signals. Here you also find the software that communicates with the board and controls it (android, unity, etc). This board is controllable via Bluetooth and compatible with any BLE device you have (such as your smartphone). It also is controllable via Serial (USB) by plugging in a USB cable from your computer to the Arduino Nano on the board.
All the necessary information for getting started is compiled in a step-by-step tutorial, start here.
The openEMSstim is a derivative by Pedro Lopes of the awesome EMS toolkit. See the License which acknowledges all the work from the original makers. This project is forked to (1) provide a simpler design with a few changes, (2) preserve the original design and credit without pulling all the changes to it and (3) be used in the UIST Student Innovation Contest 2016 without needing to change the instructions of the original project which is meant for HCI researchers and not for a UIST student audience. If you want to see the projects created by the students at UIST 2016 using this repo, see here (see the source code here).
- Read the LICENSE
- Make sure you follow the safety instructions before using it and you are familiar with all the procedure of how to apply EMS safely.
- If you are not familiar with EMS: start here (slides,papers,examples)
- Please note that this board does not generate any EMS signal, it is a amplifier that can only reduce the power of the signal you input to it. You need a EMS signal generator too, this will be your input. For your safety, use only: an off-the-shelve, un-modded, original, regulation-approved, medically compliant device.
- Please pair this board only with medically compliant EMS devices (check regulation in your country) and verify that you plug it in the INPUT port marked in the board. The OUTPUT port is connected to the electrode pads.
- Please use EMS electrodes (wet, pre-gelled and approved electrodes).
openEMSstim can be interfaced on virtually anything as long as the device features bluetooth (BT LE) or serial (USB). Here are the languages and libraries for which we have created examples and tested the code:
