Making Sensors for the IoT

Microelectromechanical systems (MEMS) is a manufacturing technology that can be used to create many different types of sensors - temperature, motion, pressure, sound, etc.- on silicon wafers. MEMS sensors serve as the eyes and ears of today’s smart connected products by acquiring information from the environment, such as the air pressure of an automobile tire or the motion of your body to record your steps.
It is anticipated that MEMS sensors will experience a rapid growth curve as the Internet of Things (IoT) makes it possible to capture the information from billions of MEMS sensors and limitations of some current simulation methods. Fortunately, it’s possible to work around these challenges using practices such as parametric analysis to understand the impact of uncertain material properties, and to integrate test results with simulation to calibrate boundary conditions. Using these and other techniques makes it possible to achieve useful simulation results that can reduce the number of fabrication (fab) rounds and bring MEMS devices to market in considerably less time and expense than is required using the traditional build and test approach.
