Imagine, when your detergent is over, your bottle will automatically connect to the wireless internete and order another bottle. For the first time, researchers at Washington University have made it possible to communicate with Wi-Fi by pressing plastic objects and sensors from a 3D printer. These include a battery-less sound control unit, a sensor that orders automatic corn flakes, and a leak-proof sensor.
Researchers from Washington University, objects and sensors written in 3D printers can communicate with Wi-Fi devices on smartphones and computers without the need for power. For example; the produced parts can be connected to the anemometer or the flow rate can be ordered when the detergent is exhausted.
With the development of wave techniques called backscattering; When the appropriate signals emitted by the Wi-Fi Router are projected from the plastics and copper mixture, they travel towards the wireless receiver. Researchers use mechanical motion to energize the 3D printed object or sensor.
The flowing water changes the reflector state of the 3D printed antenna by moving the wheel or button and moving the conductive key with the 3D printed antenna by activating or deactivating the wheels and springs. The data are encoded into the tooth's teeth and communicate with the antenna according to the length of the stance in the female key. So the signal graphics send a readable reply to the readable Wi-Fi receiver.
"When every detergent is poured from the detergent dispenser box, the speed of rotation of the impeller indicates how much detergent is active. Wireless data is transmitted between the 3D printed key and the antenna. Then the buyer calculates how much detergent is left, and when the detergent goes down, he orders it internete, "says Shyam Gollakota.
Many new battery-less and electronic devices have been designed and wirelessly connected to smart devices.
