Arizona State University (ASU) reported the receipt of a patent for a device with colorimetric sensors for measuring excreted ketones in a body fluid. Additional sensors may be incorporated to measure flow rate of the body fluid, barometric pressure, humidity, and chemicals such as oxygen and carbon dioxide present in the fluid, and a system to measure metabolic rate and respiratory quotient via oxygen consumption rate and carbon dioxide production rate.
Indigo Diabetes NV is working to develop a next-generation continuous glucose monitor (CGM) that would be much simpler and easier to use routinely, potentially making it more useful for a much larger population. It has just raised a €38 million ($44.5 million) series B financing to support that effort.
