MEMS systems include mechanical structures and electronic sense and drive circuits. Between these is an electromechanical interface, which can be capacitive, piezoresistive, piezoelectric, ferroelectric, electromagnetic, thermal, optical or can take some other form. The selection of this interface is the single most critical decision in the system definition and it determines the eventual capabilities and limits of the device.
The interface fundamentally sets the device's sensitivity, accuracy, drift, ageing, temperature behavior, and environmental capabilities. The interface determines the MEMS production technology and hence the fab selection, the cost structure, and the time to market. This tutorial examines and compares the available options and application drivers. Which interface technologies can be used? Why is one more suitable for a particular application than another? How do they scale? What is on the horizon? The goal is to expand the attendee's potential role from circuit designer to system designer. From "Here is the MEMS device, design the interface circuit." into "Here is the problem, define an optimal solution."
