ABSTRACT:
A method and a device for measuring features in a fluid such as pressure, flow rate, and temperature measurements is disclosed. The sensing device includes at least two sensing elements, all of which are 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. According to the invention the power supply and measuring circuit is controllable to feed at least two different kinds of signaling to the chip circuit. Furthermore the sensing elements are connected to each other and to the power supply and measuring circuit such that at least one of the sensing elements, controllable by the signaling from the power supply, can be individually measured. The chip is adapted to be mounted on a catheter or a guide wire.
