Before jumping to conclusions, note that the microcontroller equipped flyer is reported to be about 5cm in diameter. Not exactly size of sand grain.
From the article:
> Mechanical simulation results and photograph of a 3D IoT macroflier with a circuit to measure fine dust pollution through the light dosimetry method. The weight of the IoT flier is 19.7mg (d≈5cm), with payload 198mg (Supplementary Fig.23

- zokier 5y agoFun. Apparently HN does not filter private area unicode, and nature.com reader for some reason includes those in copypaste...
- isoprophlex 5y agoIf I search for that train in the emoji keyboard on my phone and post that, it doesn't stick... weird.
- zokier 5y agoLooking at the supplementary material, the "IoT macroflier" is pretty close to https://www.ti.com/tool/TIDM-RF430-TEMPSENSE https://www.ti.com/tool/TIDM-RF430-TEMPSENSE with some wings stuck to it.. The scale is pretty similar too, that patch is about 35mm maybe. The sensor is different (photodiode vs temperature) but that doesn't really change the overall design much.
