All-in-one bio-sensing platform

This project is coming soon. Sign up to receive updates and be notified when this project launches.

E3K is an all-in-one wireless bio-sensing framework. The platform consists of the following modules:

  • Wi-Fi- and BLE-enabled Data Communication and Processing Unit (DCPU)
  • Electromyography (EMG) sensor - to capture muscle movements
  • Electrocardiography (ECG) sensor - to capture heartbeats
  • Electroencephalography (EEG) sensor - to capture brain activity
  • 9-DOF Inertial Measurement Unit (IMU) - to capture motion

All-in-one Solution Ensures Reliable Data Acquisition

The core of the device is the Data Communication and Processing Unit (DCPU). The DCPU combined with our firmware and data collection software enables a reliable and high rate of data acquisition. This all-in-one solution includes Electromyography (EMG), Electrocardiography (ECG) and Electroencephalography (EEG) sensors to provide a well-rounded understanding of bio-signals. The device also contains a 9 DoF Inertial Measurement Unit (IMU), a few buttons, and LEDs for feedback. Moreover, our device supports all the common communication protocols like UART, I²C and SPI and provides 10 GPIO pins, 6 analog pins and 2 DAC. So you can easily develop your own hardware directly on top of the system.

Open Source Platform Encourages Innovation

The E3K platform is committed to being open source. At it’s core, E3K is designed to enable hassle-free data acquisition, so it can be easily adapted and expanded into other biosensing projects or experimental set-ups. By adding other sensors or incorporating E3K into an existing biosensing project, the platform can be used for a wide range of applications. In these difficult times, when the entire world is affected by COVID-19 pandemic, users can build innovative solutions with E3K for self-monitoring.

Designed for Easy Setup

Our original inspiration for the E3K platform came out of a frustration with a lack of any existing solution. So we designed the platform with usability in mind. Setting up our affordable platform is easy, which allows users to concentrate on the core area of work. Moreover, all interfaces are based on Commercial Off-The-Shelf (COTS) connectors so that users can extend to their project requirements with ease.

Practical Application for Biological Projects

E3K is very useful to students and researchers to build biological projects around it. Using our interactive Graphical User Interface (GUI), students can instantly visualize the signals, thus enhancing their understanding. On the other hand, using our open source data acquisition software, researchers can collect and process the data with ease. The supreme Signal to Noise Ratio (SNR) and affordable price will enable them to build their own unique solution.

Our product E3K, aims at providing a framework for an intuitive understanding of bio-signals for high school students and an affordable solution for researchers.
