An open-source data acquisition device for wearable health monitoring applications released by Glasgow Neuro Ltd. of Scotland transmits electrocardiography (ECG), electromyography (EMG), and electroencephalography (EEG) signals for processing by computers, tablets, or smartphones (see video).

The Bluetooth data acquisition device has a special focus on bio-signals such as ECG, EMG, and EEG. Source: Glasgow Neuro Ltd.The Attys system transmits raw, uncompressed signal data at 24 bits wirelessly via Bluetooth. Apps can then built that filter and process this data while maintaining the ability to see the original source.

Attys can also serve as an educational tool to measure any physical quantity such as temperature, pressure, or light intensity. It works seamlessly with Google's Science Journal and turns every Android phone or tablet into an electronic lab book/oscilloscope (see video).
