What are the saw resonators?
Acoustic wave resonators (SAW) surface waves are associated with a number of filters in Chip technology Chip frequency frequency frequency and are used in a wide range of electronic devices. These SAW filters must meet all industrial standards for use in cell phones, global positioning systems, digital satellite receivers and keyless remote controls to name at least some. SAW resonators were used in applications as diverse as wireless sales terminals, wireless tire pressure monitoring devices and microwave digital radios. They were used as biomarkers to detect markers of the disease and can even remotely stumble the presence of plastic explosives. The amplitude and speed are born in the wave of this binding, which causes the saw resonators to be able to sensitize mechanical and mass properties. This gives the saw the capacity of high frequencies for conventional ceramic and crystal resonators on the market.
On the piezoelectric substrate, such as quartz, there are metal electrodes converters as receivers, which can then receive an electrical signal and convert it to an acoustic wool, then take the acoustic wool and convert it to the electrical signal. This feedback loop creates a long delay because acoustic waves are slow and these delay makes them useful in many devices, such as filters for compression radar pulse and radio band. SAW resonators are so wide that millions of them in countries around the world are made every day.
New development has been studied for further use of saw resonators as sensors of wireless temperature measurement in harsh and isolated environmental environments. They do not need any batteries and require little periodic calibration and low maintenance. These resonators can receive and transmit wirelessly wirelessly so they can feel without invasion of high -performanceApplication for the switchboard and intelligent grid of all kinds.
Another possible way for the use of SAW resonators is in the development of wireless food probes that will replace cable food probes found in many commercial food furnaces. This could reduce the amount of salmonella, e. Coli and Clostridium pathogens from infecting people through a paddle food. Without wiring for these cable probes, the saw resonator can read and supply an antenna from built -in electronics.
Perhaps the most interesting discovery is that SAW resonators can feel markers of ovarian cancer and be used as a timely testing device for cancer, which is a quiet killer and has no test warning test since 2011. These qualities are extremely useful for robotics to use bomb units in unknown and dangerous situationsch. Thus, they can be used in the service of saving lives on two very difficult to solve fronts.
