Rong and Joe's paper on wireless addressable hazard badges has been published in Angewandte Chemie!
A battery-free, small and cheap hazard badge is developed which reliably detects a toxic gas in a concentration of as low as 28 ppb. This badge can transmit such chemical information in a binary form to a smartphone, which allows individuals to evaluate their personal exposure to chemicals. This work highlights a combination of organic chemistry and radio frequency identification technology, which involves important improvements in device structure and chemical dosimeter design.
