MEMS devices expand wireless applications in the aerospace field

in order to reduce the size, weight and power consumption of its wireless transceiver, it is necessary to have a full understanding and ideological preparation for the pain, long-term and arduous nature of structural adjustment. NASA has begun a plan to develop MEMS technology. In this plan, NASA is particularly concerned about how to reduce the volume of the wireless part commonly known as "spacewalk" for space constrained extravehicular activities (EVA)

nasa suggests that industry partners should start developing reconfigurable multi band MEMS chips that can be inserted into future software defined radio devices with flexible frequencies for use

the specifications proposed by space exploration for device suppliers are daunting, including small size, light weight, low power, radiation protection, vibration resistance and extremely long service life. Fortunately, these indicators seem to be basically consistent with the definition of MEMS, so researchers have been using MEMS since the earliest space shuttle launch

"I would be surprised if our MEMS devices were not used in any space shuttle launch." Said Harvey Weinberg Sr., application engineer of Analog Devices Corporation (ADI)

the market size of any aerospace application is very small, because the number of spacecraft launched each year is very limited, and the MEMS market for aerospace is no exception. But on the other hand, the technology developed by NASA in advance will slowly extend to the military and commercial fields. Take Teflon as an example. Although it was first used as a coating for the fire-proof shell of spacecraft, it was later used for kitchen utensils such as pots and pans of ordinary consumers. However, experiments can only be carried out after this. This development path is just the opposite for MEMS

"for many MEMS devices, their applications first appear in the commercial and military fields." John Vig, a 36 year old senior military researcher, pointed out. Vig suggested that the defense advanced technology research program (DARPA) implement the RF MEMS development program. "DARPA has a very aggressive RF MEMS program, and I'm sure many DARPA developers also want to submit relevant suggestions to NASA." Vig revealed

MEMS specifications for ground vehicle applications can also meet the requirements of space exploration. After all, the safety of drivers and passengers in cars is not much different from that of astronauts in spacecraft. Moreover, automotive applications generally require a life span of at least 15 years. On the whole, this can also well meet the long-life requirements of outer space exploration

"MEMS sensors developed specifically for harsh environments (such as automotive, military and telecommunications markets) have also been increasingly widely adopted in aerospace applications." Garner/dat does a good job in the auto parts industry, said Jim walker, vice president of semiconductor manufacturing at quest
