‘University of Washington’ Researchers Discovered 3D-printed Objects, that doesn’t need Batteries to Stay Online

A new project has been discovered by at the University of Washington, which will help guide the creation of gadgets that donR7;t require any power at all to stay online.

Vikram Iyer, Justin Chan, and Shyamnath Gollakota from UW figured out a way to 3D-print plastic objects with wireless capabilities baked right in – no power source or electronics necessary.

The trio created a weighing scale, a flow sensor, and an anemometer that measures wind . They used composite plastic that contains conductive filament materials like copper and graphene fillings; to encode bits of data, they used gears (0s and 1s are represented by the presence and absence of teeth, respectively) – and transmitted said data using Wi-Fi backscatter, which allows for communication by modifying the reflection an incident Wi-Fi signal.

So, basically, they’ve created sensors that can beam data to your phone or other connected devices without the need for any sort of circuitry. The group also created a Tide bottle that detects how much detergent is left in it, as well as knobs and sliders for wireless input to scroll through webpages, and even an Amazon Dash-style – all 3D printed and battery-free.

Their work could allow for the creation of smart devices that are not only more environmentally friendly, but also less of a hassle to own and maintain. You can check out the researchers’ paper on this page (PDF), and watch a demo above.
