MEMS sensors for smart infrastructures

07 October 2019

Tablets, smartphones, video game consoles, camcorders, and cameras have revolutionised the world of sensors. This includes MEMS accelerometers and gyroscopes. Their ability to measure movement has led to improved performance and increased the functionality in many of the devices in which they are used.

While consumer applications have spurred demand for these sensors, their use in other markets is also increasing. With the advent of digitisation, or the Internet of Things, sensors are becoming central in industrial infrastructure applications. In these instances, MEMS are being relied upon for condition monitoring and structural health monitoring. With these new applications come very specific standards for performance and reliability.

Smart infrastructure

Using digitisation to create smart infrastructure offers a number of benefits. Among these are increased capacity, efficiency, and reliability. Smart infrastructure enables additional and more targeted services to customers and users, without increasing investments or resources. In addition, a connected infrastructure can gather data to help design and implement future infrastructure more efficiently. Bringing intelligence to infrastructure can also effectively address the major challenge of maintenance. MEMS sensors play a decisive role in structural health monitoring. They can be used to measure inclination variations, vibration analysis, and linear or circular movements – even in extreme conditions. These sensors make it possible to carry out predictive maintenance, making better use of available resources and helping to avoid service failures and interruptions. Analog Devices has invested heavily in MEMS technology that can support smart infrastructure applications.
