Piezo-Based Energy Harvesting May Repel Tooth Decay

I’ve always been interested in small-scale energy harvesting projects. After all, it seems like the almost ideal “something for nearly nothing” arrangement. Get a suitable transducer, power-management IC (PMIC), an energy storage component (rechargeable battery or supercapacitor) and you’re all set when you need to power a remote node, an IoT device, or other low-power devices. Of course, there are also large-scale harvesting such as wind, solar, or geothermal power, but those projects are at a very different scale, while small-scale harvesting seems more personal and non-intrusive.
