Non-contact EXG trodes
This project is very important to us. With it starts a new era for our team, we go from freelance to development of our own devices, which will be focused on human augmentation – first by acquiring information about our own body, later by enhancing our physical, and, hopefully, also cognitive abilities. For the long time we wanted to do it, but thought it is too complicated and we need to know more and do some simpler stuff. Now we believe it’s the right time to actually start this – apparently, technology in this area won’t develop itself.
So here is our first step: maker-friendly system of EXG electrodes for measuring just any electrical signals our body generates – muscle signals (EMG), heart activity (ECG), brain electrical patterns (EEG).
Maker-friendly is the main point of this project: we want to create something that people can actually use for any purpose with simple way to attach it to other hardware and with zero complications in getting raw data for analysis.
In order to do this, we transmit all obtained data using nrf24 radio chip, which is well supported by Arduino community. Arduino code that is required to receive and transmit these data into PC fits in less than 50 lines (we actually use Arduino board to get data even during development to ensure that it won’t ever get complicated).
And it goes without saying that all PCB design, module API and any code we’ll write for data analysis will be open source. Right now it’s too far from being finished to publish it, but we’ll get there.
