Collecting and transmitting biomedical telemetry has never been easier. You can integrate a few off-the-shelf integrated circuits to collect data like ECG waveforms, pulse oximetry, and temperature. Add a few more off-the-shelf parts, and you can fling that data anywhere in the world across the internet.

The vast majority of medical devices with electronics contain some sort of embedded processor running firmware. There are a range of modern techniques that can be used to facilitate better reliability of embedded firmware. One that I’m a big fan of is unit testing. Embedded engineers opposed to unit testing will raise a few common […]
Last week my blog discussed a major drawback to multi-layer ceramic chip capacitors (MLCCs) that is poorly understood by even experienced engineers: DC bias effects on capacitance. So, now that we know that DC bias effects can be significant: what can we do about it?
Multi-layer ceramic chip capacitor MLCC are the most common capacitor found in modern electronics. MLCCs have many attractive features: low ESR, good capacitance-to-volume ratio, relatively low leakage, non-polarity, and low cost. It’s no wonder that when choosing a capacitor, an electrical engineer will usually specify a ceramic first before any other type. However, there is […]
Smart watches, near field tags, fitness trackers – everywhere you look, electronics are getting smaller. Medical devices are no exception, with many medical device manufacturers targeting very small form-factors for their devices. When miniaturizing a device’s electronics, there are several approaches.
