Whilst Jawbone and Fitbit offer very a stylish design and amazing looking visualisation to monitor health and fitness, if you are a developer/researcher, you are pretty much stuck with the pre-processed data they give you. These devices do not provide open access to the raw data. My colleague and I are working on a project on epilepsy seizure monitoring, and we are looking for a wristband sensor device that allows us to extract raw data. Fortunately I came across “Angel!” Angel seems to provide raw waveform data for heart sounds, optical blood flow, and 3D acceleration. It allows researchers and developers to carry out advanced processing. It is a project funded through www.indiegogo.com, and I hope it delivers what it promises.
