Cover Feature: Ultra‐Sensitive and Ultra‐Stretchable Strain Sensors Based on Emulsion Gels with Broad Operating Temperature (Chem. Eur. J. 52/2021)

Abstract

Taking the strain: An emulsion gel with high stretchability and conductivity was fabricated and could be used as a strain sensor to detect human motion over a broad operating temperature. First, an emulsion that was ultra-stable at high and low temperatures was prepared by introducing glycerol into a W/W emulsion. Then, the continuous phase was polymerized to produce a macroporous emulsion gel. Finally, an emulsion-gel-based strain sensor with good flexibility, conductivity, self-healing, and adhesion properties was fabricated to detect the full range of human body movement. The sensor exhibited remarkable sensing sensitivity, rapid responsiveness, and reliability. For more information, see the Full Paper by J. Hao et al. (DOI: 10.1002/chem.202101472).
