Gas Sensing: Scalable Superior Chemical Sensing Performance of Stretchable Ionotronic Skin via a π‐Hole Receptor Effect (Adv. Mater. 13/2021)

A skin-attachable chemical sensor showing high sensitivity, selectivity, stability, and even scalability is demonstrated by Ming Liang Jin, Hee-Tae Jung, Chi Won Ahn, Do Hwan Kim, and co-workers in article number 2007605, which they term an ionotronic gas-sensing sticker. Ultimately, the proposed strategy is expected to provide new guidelines for sensing channels for next-generation wearable gas-sensor platforms.
