Bacterial Cellulose-Stabilized Liquid Metal Enables Stretchable Poly(acrylic acid) Strain Sensor
Conductive hydrogels with simultaneous high stretchability, robust mechanical toughness, and reliable strain-sensing sensitivity remain challenging to fabricate, particularly without toxic chemical initiators or cross-linkers. To address this, a multifunctional poly(acrylic acid)/gallium-bacterial cellulose (PAA/Ga-B...
