Articles with tag 'Bloodlight'
The Bloodlight project was designed to test for new health metrics in the blood by testing multiple LED wavelengths of light at high-frequency and accuracy. We hoped to process the signals to determine the most appropriate wavelengths for low-power sensing and find new potential data in the signals.
One of the more challenging aspects of prototyping research hardware has always been the construction of plastic enclosures/cases. This is an even more fundamental issue for wearable/medical prototypes - in our example the case plays a strong role in the PPG sensor's optical properties.
Codethink is working on a project to design a fully open-source (hardware and software) research device for experimenting with shining light into skin and detecting the light that reflects, gets absorbed and passes through. This kind of technology is widely deployed for measuring heart rates.
