Dulog Bio-Tracker, Powered by Silicon Labs' EFR32 SoCs, Proves Bats Can Socially Distance When Sick Proven in the field, and with a commercial implementation coming soon, the dulog bio-logger proves how smart bats can be. 2 2 Silicon Labs has highlighted a somewhat unusually-deployed wireless network, built using EFR32 "Wireless Gecko" systems-on-chips (SoCs) â attached to the backs of bats, as part of a study to see whether the flying mammals practice social distancing. "Iâve been involved with this project since the end of 2013 and was inspired by my advisor, who is also a bat biologist," Ohio State University biologist Simon Ripperger explains in an interview with Silicon Labs. "He used to go to Greece for field work all the time, but their method of tracking and bio-logging bats was a bit unbelievable â he was essentially running behind bats, chasing them with an antenna."
