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

The Flashing Light Prize Returns

Delightfully bonkers award issues call for ingenious and unusual ways of flashing a bulb, tube or other vessel that contains neon gas. The inaugural Flashing Light Prize sought novel approaches to flashing an incandescent light bulb — and the entries certainly did not disappoint, with the winner… Read More
