New non-contact EXG electrodes
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
control band
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
EXG electrodes
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)
Robotic arm prosthesis
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
realtime ECG monitor with 2G
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
EMG sensors
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.
tool tracker
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.
