[From the last episode: We looked at how to build a simple accelerometer.] Before we talk more about accelerometers and other so-called inertial measurement units, we need to hit on one important generic concept: the notion of “degrees of freedom.” If this is a familiar concept to you, you probably […]

[From the last episode: A full sensor contains the basic transducer plus circuitry to clean things up and, usually, convert to digital.] Here we take a look at our first real sensor: the accelerometer. Like the name suggests, it measures acceleration. This was actually the first sensor application to be […]

[From the last episode: We looked at the many steps required to dig a swimming pool using only MEMS-like techniques.] Before we take a look at some specific kinds of sensors, let’s talk a bit more about MEMS processing, since it’s incredibly versatile. There are a couple things that are […]

[From the last episode: We looked at the normal way to build a pool, and then looked generically at what’s different when you use a MEMS approach.] What follows echoes (but is not identical to) a piece I did for EE Journal way back in 2011. Because that audience is […]

[From the last episode: MEMS technology has been critical for enabling micro-scale sensors and actuators.] A first warning: this post and the next one may tax your imagination. So buckle up! We’ve seen the basic processing steps needed to make things on silicon: deposition, etching, and litho. When these are […]
