What is E3K?

E3K provides wireless framework for an intuitive understanding of bio-signals originated from the human heart, muscle, and brain. There are several modules, including electromyography (EMG) sensor - to capture muscle movements; electrocardiography (ECG) sensor - to capture heart signals; electroencephalography (EEG) sensor - to capture brain activity; and 9-DoF Inertial Measurement Unit (IMU) - to capture motion. Combined with modules, it enables a reliable and high rate of data acquisition. It it a kind design for people who are working with bio-signal acquisition, they can use it directly as well as customization. Also, it is very useful and suitable to students for its affordable price.


Modularity naturally allows you to configure E3K into the bio-signal acquisition tool that you need. Use the modules you need, in the configuration you need them. Or you can add your own modules!

E3K supports widely used communication protocols like UART, I2C, and SPI and provides 10 GPIO pins, 6 analog pins, and 2 DACs. So you can easily develop your own hardware directly on top of the system.


The E3K GUI allows you to configure each channel and collect data without requiring any coding. But for advanced users, it can be programmed either by using Arduino IDE or Espressif IDF.

Arduino libraries and Python APIs are in the development, so that anyone can integrate the E3K platform into their own projects. These codes, along with the hardware schematics, will be shared on GitHub repo once the campaign concludes.
