Wind-Propelled Flying Microchip Measures Air Pollution
Researchers have assembled the world's smallest flying structure, a tiny microchip that travels like wind-dispersed seeds with onboard technology to track air pollution and airborne diseases.
Supported by grants from the National Science Foundation, the team demonstrated the flier’s ability to use sensors, memory storage and an antenna that can wirelessly transfer data to a smartphone or tablet. In addition to air monitoring, they’re working on a model outfitted with pH sensors that could be used to measure water quality. Looking ahead, the team plans to build the microfliers from biodegradable electronics materials that would dissolve in groundwater over time.
