Abstract:
1. Sensing device for measuring at least two features, wherein said features include pressure and temperature, flow rate and temperature or pressure, and flow and temperature, in a fluid, comprising at least two sensing elements all mounted and/or fabricated on a chip and connected to a chip circuit, and a power supply and measuring circuit placed outside the chip and connected to the chip circuit, wherein the power supply and measuring circuit is controllable to feed at least two different kinds of signaling to the chip circuit; and in that the at least two sensing elements are connected to each other and to the power supply and measuring circuit such that at least one of the sensing elements in dependence of the different signaling from the power supply could be individually measured, and in that the chip is adapted to be mounted on a catheter or a guide wire.
