摘要: An acoustic wave sensor apparatus is disclosed, which generally includes a piezoelectric substrate having a surface thereon. One or more interdigital transducers and a passivation layer can be formed upon the piezoelectric substrate. Additionally, an absorbent material can be formed upon the acoustic path (IDTs, electrodes, etc), such that the interdigital transducers respond to a plurality of acoustic waves propagating across the surface of the piezoelectric substrate, thereby providing data indicative of humidity in the vicinity of the piezoelectric substrate, along with the passivation layer and the interdigital transducers. Additionally, one or more heaters can be formed upon a side of the piezoelectric substrate opposite the side of the piezoelectric substrate upon which the interdigital transducers, the passivation and the absorbent material are located. The heater can be preferably configured from a material such as platinum.

摘要: Circuits for the restoration of a drooped signal are disclosed. In the asynchronous mode circuit, the drooped signal can be restored by detecting the peak of the positive amplitude and the peak of the negative amplitude and take the difference between the two peaks. This difference signal is fed back the equalizer. In the synchronous mode circuit, the drooped signal is sliced and passed to a regeneration circuit. The regeneration circuit uses reference voltage signals and phase information from the slicer to generate a regenerated signal. The regenerated signal is compared with the equalized signal to generate a difference signal, again fed back to the equalizer. The sliced signal is also fed to a clock recovery circuit which recovers the clock signal embedded in the received signal. The two circuits can be combined to provide an optimal circuit for the restoration of a drooped signal.

摘要: Many sensors could be used in a passive wireless mode. These include RLC, acoustic wave and magneto-elastic sensors. These types of sensors are designed to exhibit a change in fundamental frequency when exposed to environmental factors such as temperature, pressure, or chemicals. An interrogation circuit can inductively couple to the sensor and measure the change in fundamental frequency. The change can be used to measure the environmental factor. Sensor sensitivity and inductive coupling efficiency can be competing design constraints. A driver, electrically connected to the sensor and inductively coupled to the interrogation circuit, can relax the constraints. The driver, however, can introduce noise into the sensor. The sensor can be shielded using physical and geometric techniques to reduce the noise.

摘要: A SAW/BAW hybrid sensor is a sensor that combines the ease of interfacing with a higher frequency of SAW device and the response, precision, ease of use with liquid applications and dynamic range of a BAW sensor. The SAW device can condition an interrogation signal before passing it to the BAW sensor. For example, the SAW device can act as an impedance matcher or a frequency shifter. The hybrid sensor can be created by connecting the electrodes of a BAW sensor to a SAW device transducer. The hybrid sensor can be interrogated via any of the common interrogation circuits such as a grid dip oscillator or a RADAR type interrogation system.
