Electronic upcycling of corn straw: bio-based, elastic, conductive, cross-linked, eco-friendly hydrogels with multifunctionalities for flexible wearable sensors

Corn straw is the base material for the hydrogel, which realizes the upcycling of agro-waste into a flexible sensor. The as-prepared gel is sensitized to temperature, humidity, strain, and is eco-friendly with recyclable and degradable properties.
