3D-printed plastic objects have been developed by the researchers at the University of Washington. These objects will be used to transmit information via WiFi without the use of electronics or batteries. They indicated that it can be achieved with commercially available plastics and WiFi receivers. A graduate student on the project, Vikram Iyer said in a statement that their major objective was to create something just come out of your 3D printer at home and can deliver essential information to other devices. But, there was a major challenge for communicating wirelessly with WiFi using just plastic. It was the actual scenario by which anyone hasn’t yet able to do it. The team used some essential items including 3D-printed springs, switches and gears that could be used motion translation into antenna-transmitted information in order to start their experiment.
For instance, they formerly created a scale and a flow-meter in order to measure water speed. They also created an anemometer in order to measure wind speed. It was attached to a gear and after spinning the gear, the teeth connect with an antenna attached into the object. The antenna then reflects enveloped WiFi signal and then decoded by a WiFi receiver. Massive amount of wind will spin the gear faster and those signals will be transmitted more speedily. They have also printed 3 widgets, including a button, a slider and a knob. It works in similar ways and can be used to communicate with other smart devices. The researchers also created 2 smart objects, a detergent bottle with an attached flow-meter. It has the ability to track remaining quantity of detergent and order it after decreasing a significant amount of specified level. Finally, they developed a method to print iron into 3D-objects in specific patterns and can be read by a magnetometer in a smart-phone.
