[From the last episode: We can design an accelerometer that measures all three dimensions, or degrees of freedom.] OK, so, so far, we’ve seen that we can use small movements in our accelerometer proof mass to detect acceleration. And we can tell how much acceleration there is by how much […]

[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 […]
