Lab-On-Chip Flow and Temperature Sensor

NASA Goddard Space Flight Center has developed a sensor for microanalytical systems that measures, in real time, the flow rate and temperature of the liquid being sampled. Current sensors divert the liquid to separate temperature and flow sensors, which can result in fluid leakage and the need for a larger initial sample. This design eliminates that diversion. The system sensors measure flow rates in the nanoliter-per-minute range and temperatures from greater than 150 °C down to below -80 °C.
