[From the last episode: We can measure inertia in six independent ways (degrees of freedom): 3 in a straight line and 3 with rotation.] We saw a couple posts ago that we can build an accelerometer that senses when we move up or down. But last time we saw that […]

[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: There are many choices available to designers when implementing MEMS technology.] We’ve talked enough about one way to build basic sensors, but the kind of sensor you could buy from a store (although exceedingly few retail outlets would sell them) is more than just the MEMS […]

[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 […]
