  • Wearable bioelectronic facemasks integrated with ion-gated transistors
  • A highly stretchable ion gel serves as the dielectric layer for flexible transistors
  • Trace liquid samples (0.3 μL) and gaseous media samples can be measured
  • A universal, real-time detection platform for various respiratory infectious diseases

Progress and potential

Developing wearable electronics capable of detecting viruses directly from airborne media is crucial for rapidly diagnosing respiratory infectious diseases. However, wearable sensor platforms for analyzing airborne media remain underexplored. Here, a wearable bioelectronic mask device integrated with ion-gated transistors is developed for testing viral proteins. A stretchable ionic gel synthesized by a two-solvent system works as a dielectric layer for the ion-gated transistors. 
The device can detect trace liquid samples and gaseous media samples. Advantages of low detection limit (0.1 fg/mL), rapid response (10 min), and multi-channel analysis make the bioelectronic mask a versatile detection platform for various respiratory infectious diseases. 
The integration of internet of things technology facilitates real-time on-site detection of surrounding air. This wearable bioelectronic mask is expected to serve as an early warning system to prevent outbreaks of respiratory infectious diseases.

DJ ...this can become a way out of the pandemics...eventough it will be a race against time....Also new nasal vaccines may provide sterilizing immunity...welcome developments...
