Facile Fabrication of Stretchable Microgroove-Crack-Based Strain Sensor with High Sensitivity and Low Detection Limit

Strain/pressure sensors utilizing advanced nanomaterials

“…Moreover, a stretchable strain sensor based on Ag NPs/multi‐walled carbon nanotubes composites was fabricated using an aerodynamically focused nanomaterials printing system, exhibiting high sensitivity and a wide measurable range with high mechanical stability 44 . To improve the sensitivity, a highly sensitive flexible strain sensor was developed using a network of metallic NPs grown under vacuum on top of a cracked thin alumina film, reaching a record strain sensitivity value while exhibiting high sensitivity in a large strain range 45 …”

“…The band‐gap opening of the GE/g‐C3N4 matrix is observed from 0.19 to 2.46 eV when applying −12% to 20% uniaxial strain. When GE foam is contained in elastomer, the resulting composites can be stretched to 95% of its original length before mechanical breakage 45,50 . Also, carbon nanotubes (CNTs) and GE can be combined to exhibit synergetic effect, due to their unique properties 64 .…”
