3D Printed Wi-Fi Backscatter Sensor

Researchers Demonstrate 3D Printed Passive Wi-Fi Sensors

Researchers from the University of Washington have demonstrated wholly passive, electronics-free Internet of Things [IoT] sensors, produced on commodity 3D printers, which are nevertheless capable of transmitting data to nearby Wi-Fi receivers. Based on similar backscatter principles as radio frequency identification (RFID) tags, Vikram Iyer and Justin Chan’s work takes… Read More
