Indian Researchers Create a Raspberry-Pi-Based Device To Monitor Health

Two researchers in India have developed a new blood test that is simple, affordable, and easily deployed anywhere where a source of electricity is available. IEEE Spectrum reports: Sangeeta Palekar is a researcher at Shri Ramdeobaba College of Engineering and Management (RCOEM) who helped devise the new design. She and her colleague, Jayu Kalambe, understand how powerful a simple blood test can be. "Routine blood tests can help track and eliminate the threat of many potential diseases," explains Palekar, noting that blood tests make up roughly one-third of all pathology laboratory tests. [...] [The new analyzer] involves an automated fluid dispenser that adds a controlled amount of reagent into the blood sample. Light is then passed through the sample, and a Raspberry Pi computer analyzes the data. The system can be adapted to analyze any biochemical substances in the blood by simply modifying the reagent and spectral wavelength that's used. [...] When comparing the data obtained by their biochemical analyzer to the known results obtain by standard laboratory equipment, they found the data matched almost perfectly. What's more, the device could yield accurate results in just half a minute. The researchers describe the results in a study published in IEEE Sensors Journal.
