Abstract
At least one embodiment is directed to a sensor for measuring a parameter. A signal path of the system comprises an amplifier (), a sensor element, and an amplifier (). The sensor element comprises a transducer () at a first location of a waveguide (), and a reflective surface () at a second location of the waveguide (). A parameter such as force or pressure applied to the sensor element can change the length of waveguide (). A pulsed energy wave is emitted by the transducer () into the waveguide () at the first location. The transducer () is responsive to pulsed energy waves reflected from reflective surface () to the second location. The transit time of each pulsed energy wave is measured. The transit time corresponds to the pressure or force applied to the sensor element.
