uECG is an open source, open hardware platform for research and DIY projects involving ECG measurements. It is also super lightweight - less than 10 grams including battery- so it provides reasonably clean readings during physical activity. uECG transmits raw data to smartphones via BLE, also it can transmit data

These are non-contact electrodes – meaning they don’t need galvanic skin contact to receive signal, capacitive coupling is used instead. Sensor has isolated copper area on one side, which when placed close to the skin creates a small capacitor receiving any AC signals from the body. Signal transfer is the

After making our hexagon and triangle modules of EXG electrodes, we needed a way to fit these to an arm. First, we fixed them with kinesiology tape and made a simple interface to highlight active muscles: This wasn't comfortable to wear though, and also wasn't easily removable. This wristband version

status: ongoing progress: 80% prototype: yes, MK6 type: open-source These sensors are our first project in augmentation (biotech): 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: we want to

Long term volunteer project with quite ambitious goal of creating reliable, cheap and extremely capable prosthetic hand that can be controlled via multiple surface EMG devices (ability to reliably achieve multiple degrees of freedom with EMG has highest priority for us).

One of the larger commercial projects for a hospital - the task was to develop a standalone ECG monitor that patients could wear at home for a standard Holter test. Previous monitors were bulky and required a Bluetooth connection (on a separate smartphone with special firmware and app) to wear

Electromyography sensor – part of prosthetic hand project, we made several iterations since early 2015. Older versions had single galvanic channel, then 2-channel low-noise version was completed, currently non-contact (capacitive sensing) version is in development.

Did we already tell you how we liked projects with LEDs? Well, we made another one, and it's small and round. This time it's for movement and position tracker.

This is by far our most complicated medical project - it was made for a client with a lot of ideas, who was willing to move very fast, but unfortunately stopped listening to the team despite our best attempts to explain that some things were plain unreachable or couldn't be

Near-infrared spectroscopy device for measuring muscle oxygenation level. Research/semi-commercial project with main goal to make a device to research efficiency of various probe configurations and wavelengths for obtaining as much information as possible using variations in light absorption on different light frequency. Included WiFi transmission of obtained data and

Who doesn't like a project with LEDs! We certainly do! For this one, we needed to invent a solution for tracking ball hits on the net and producing visual feedback, so the players could train. Basically, blink the LEDs to show where you hit and how precisely. We made a

A small inexpensive CO monitor. We made an instructable for it.

Commercial/research project, currently in progress so we can’t really share details. Our goal is to create a robot acting as a sport partner. Basically it is a high speed and high power 3-wheel platform equipped with several IR distance sensors (to prevent unexpected collisions), lidar, inertial navigation unit,

Another project with the same Arduino+Raspberry approach with video and control over WiFi that we used in hexacopter. We used non-typical configuration of legs and developed our own inverse kinematics algorithm, optimized for calculations on Arduino (using several simplifications, all 18 servo positions were calculated in less than 10
