The second electrical signal is based on at least one parameter monitored by the sensor. The apparatus also includes an antenna that converts first wireless signals into the first electrical signal and that converts the second electrical signal into second wireless signals. The antenna includes a substrate, conductive traces, and conductive interconnects. The conductive traces are formed on first and second surfaces of the substrate. The conductive interconnects couple the conductive traces, and the conductive interconnects and the conductive traces form at least one helical arm of the antenna. The conductive traces could be formed in various ways, such as by etching or direct printing.

摘要： A vacuum sealed SAW pressure sensor is disclosed herein, which includes a sensing element configured as a SAW device (e.g., SAW resonator or SAW delay line) supported by a thin diaphragm. The substrate material can be implemented as a quartz wafer (i.e., a “base” wafer). The SAW device can be configured on one side of the wafer and the diaphragm etched on the opposite side. A quartz micromachined pressure sensor can thus be realized, which operates based on a variation of the surface wave velocity of a SAW device situated on the thin diaphragm. The SAW sensor is generally sealed in a vacuum and diaphragm sustains the sensor, thereby implementing a sensor on a wafer scale while allowing for a cost reduction per chip.

摘要： A SAW-based micro-sensor apparatus for simultaneously monitoring acceleration/vibration and temperature utilizing a sensing element configured as a SAW device (e.g., SAW resonator or SAW delay line). The SAW device can be located in different locations on a substrate with respect to a thin piezoelectric diaphragm comprising an inertial mass. The temperature-compensated acceleration/vibration can be measured utilizing a frequency difference between an acceleration sensitive SAW resonator (e.g., SAW-g) and a temperature sensitive SAW resonator (e.g., SAW-T). The temperature can be measured utilizing a frequency shift provided by the SAW-T and a temperature reference SAW resonator (e.g., SAW-R). Similarly, the phase response of different reflectors of the SAW delay line can be utilized to differentially measure the acceleration/vibration and temperature.

摘要： A piezoresistive pressure and/or strain sensor micro-machined primarily from plastic and/or glass. In one illustrative embodiment, the piezoresistive pressure sensor is formed on a polymer substrate. A first selectively implanted region is provided in the polymer substrate to create a piezoresistive region in the polymer substrate. A second selectively implanted region is then provided in at least part of the first selectively implanted region to modulate the electrical conductivity of the first selectively implanted region. The illustrative sensor may be selectively implanted with, for example, nitrogen to create the piezoresistive region, and boron to modulate the electrical conductivity of the piezoresistive region. Phosphorus or any other suitable material may also be used to modulate the electrical conductivity of the piezoresistive region, as desired. The piezoresistive pressure/strain sensor may be formed from a single substrate, or two or more substrates, and the resulting pressure/strain sensor may be mounted in a plastic package, if desired.
