In the last decades, many technological progresses have been made in this area and MEMS accelerometers are used in high-reliability environments and are starting to replace other established technologies.

MEMS accelerometer can be applied as a sensor in the earthquake disaster prevention, since one of the main characteristics of MEMS accelerometers is the linear frequency response to DC to about 500&nbsp;Hz, and this capability offers an improvement in measuring [[ground motion]] at lower-frequency band.<ref>{{Cite journal |last1=Aizawa |first1=Takao |last2=Matsuoka |first2=Toshi |last3=Kimura |first3=Toshinori |last4=Takeda |first4=Tetsuya |date=2008 |title=Application of MEMS accelerometer to geophysics |url=https://www.researchgate.net/publication/43195901 |journal=International Journal of the JRCM |volume=4}}</ref>

Another practical application of MEMS accelerometers is in machine condition monitoring to reduce machines’ maintenance. Wireless and embedded technologies such as Micro-electro Mechanical system sensors offer a wireless smart vibration measurement of machine’s condition.<ref>{{Cite journal |last1=Albarbar |first1=Alhussein |last2=Mekid |first2=Samir |last3=Starr |first3=Andrew |last4=Pietruszkiewicz |first4=Robert |date=2008 |title=Suitability of MEMS Accelerometers for Condition Monitoring: An experimental study |url=https://www.mdpi.com/1424-8220/8/2/784/pdf |journal= Sensors|volume=8 |issue=2 |pages=784–799 |doi=10.3390/s8020784 |pmid=27879734 |pmc=3672998 |bibcode=2008Senso...8..784A |doi-access=free }}</ref>

Moving to the [[arms industry|defence]] field, it can be applied in fence-mounted intrusion [[detection]] systems. Since MEMS sensors are able to work in a wide temperature range, they can prevent intrusions in outdoors and very spread-off perimeters.
