Researchers developed a photolithography-compatible electroforming process that co-deposits mechanically fibrillated cellulose nanofibers with carboxymethyl cellulose to create thin, free-standing microscale structures. The composite films averaged about 4.2 GPa in Young’s modulus, while a 300 nm suspended bridge resonated at 23.34 kHz under vacuum, with modeling indicating residual tensile stress from constrained drying.
