    摘要： Sensor systems and methods are disclosed herein, including a sensor chip, upon which at least two surface acoustic wave (SAW) sensing elements are centrally located on a first side (e.g., front side) of the sensor chip. The SAW sensing elements occupy a common area on the first side of the sensor chip. An etched diaphragm is located centrally on the second side (i.e., back side) of the sensor chip opposite the first side in association with the two SAW sensing elements in order to concentrate the mechanical strain of the sensor system or sensor device in the etched diagram, thereby providing high strength, high sensitivity and ease of manufacturing thereof.

    摘要： Disposable pressure sensor methods and systems are disclosed. A substrate can be provided, along with a capacitor and an inductor fixed to the substrate to form a pressure sensor thereof. In a variable L configuration, the inductor can be configured to comprise an inductor surface and a diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the inductor surface, thereby resulting in an increase in the inductance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. In a variable C configuration, the capacitor can be configured to comprise one electrode on the surface and one on the diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the capacitor surface, thereby resulting in an increase in the capacitance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. Such increase and/or decrease data are detectable by external interrogation.
