Dr. Bernd Porr has also shared the following open source bioamplifier:
“Attys is an open source wearable data acquisition device with a special focus on biomedical signals such as heart activity (ECG), muscle activity (EMG) and brain activity (EEG). In contrast to many neurogadgets, the Attys transmits the data as it’s being recorded without any compression or pre-filtering, and at its full precision of 24 bits, to a mobile phone, tablet or PC. This guarantees maximum possible openness so that the raw data can be published alongside the processed data, as required now by many research councils.
All software for the Attys is open source which includes the firmware of the Attys.
The story of the Attys started four years ago, when Dr. Bernd Porr filmed numerous YouTube clips to educate the public about the possibilities and limits of biosignal measurement (see BPM Biosignals). The site has been very popular ever since and visitors have been asking if a ready made bio-amp could be made available. This was the birth of Attys.”
