摘要: A smart acidochromic agarose-based film with 1,4-bis(para-hydroxystyryl)benzene as the pH-responsive fluorophore was prepared. This can simultaneously harness chemical potential of light and aerial humidity gradients to convert them into mechanical work. The strong reversible hygroscopicity agarose matrix induces swift locomotion by deformation owing exchange water surroundings. Driven humidity, a 20 mg composite coupled piezoelectric bending transducer sensor generates peak output approximately 80 mV, which corresponds power density 25 μW kg(-1). Excitation UV triggers isomerization chromophore, appears reshaping spiraling, bending, or twisting film. material also responds changes in pH value protonation rapid color fluorescence. threefold sensing capability this could be utilized for fabrication multiresponsive actuating dynamic elements biomedicine soft robotics.
