WARF TECHNOLOGIES

UW-Madison researchers, in conjunction with an industry partner, have developed a printed serpentine trace that can act as both a temperature sensor and a strain/flow sensor. It is integrated on a single deformable substrate that can be input into a flowing liquid. As the liquid flows, the deflection of the substrate is modified. The sensor has three terminals set up in a voltage divider conformation to obtain resistance values from both the temperature sensing portion and the strain sensing portion. This invention could be a low-cost, highly integrated solution for in-flow rate and temperature measurements.
