In 2013, the GTPG partnered with the Children’s Hospital of Atlanta’s Pediatric Innovation Seed Grant program to develop what colloquially became known as “wireless diapers”. The thin, low-cost, flexible inset could be placed inside of a diaper or a garment and read by a standard 915 MHz RFID reader. With two diversity antennas and a capacitive moisture sensor, the sensor could reliably power up and measure moisture — even while worn by the user.
The final video in the Wireless Without Batteries Series, involving low-powered sensors used for localization, tomography, and telemetry. This concludes the 2017 lecture series that was delivered on the Georgia Tech campus in Shenzhen, China.
WWB19: Tomography and Sensing
Dylan Crocker has graciously provided some original code for generating arbitrary versions of sinuous antenna GIF files. The MATLAB code can be downloaded here: draw_hypnotic_sinuous.m. The one from earlier in the week was a screen grab from Dylan’s proposal, incrementally rotated in Adobe photoshop frames. Please pass along any other psychedelic antenna designs to durgin at gatech.edu and I will post them.
