Roll stamped Ni/MWCNT composites for highly reliable cellulose paper-based strain sensor

Bacterial Cellulose-Based Biomimetic Composites

Printable cellulose-based electroconductive composites for sensing elements in paper electronics

Conductive flexible hydrogel composites were printed on paper substrates using a functional ink, whichwas designed and formulated for screen-printing. The inkswere prepared using abundant and eco-friendlymaterials by blending carbon fibers into thematrix of a water-soluble cellulose derivative, carboxymethyl cellulose. For an optimal concentration of carbon fibers (10wt.%), the printed patterns...

Thermoresistive Strain Sensor and Positioning Method for Roll-to-Roll Processes

This study uses the Joule heating effect-generated temperature difference to monitor in real-time and localize both compressive and tensile strains for the polymer substrates used in the roll-to-roll process. A serpentine gold (Au) line was patterned on a polyethylenenaphthalate (PEN) substrate to form the strain sensor based on thermoresistive behavior. This strain sensor was then subjected to...

Highly Sensitive and Stretchable Strain Sensor Based on Ag@CNTs

Due to the rapid development and superb performance of electronic skin, we propose a highly sensitive and stretchable temperature and strain sensor. Silver nanoparticles coated carbon nanowires (Ag@CNT) nanomaterials with different Ag concentrations were synthesized. After the morphology and components of the nanomaterials were demonstrated, the sensors composed of Polydimethylsiloxane (PDMS) a...

Highly transparent and writable wood all - cellulose hybrid nanostructured paper †

Paper, as an inexpensive substrate for flexible electronics and energy devices, has garnered great attention because of its abundance, biodegradability, renewability and sustainability. However, the intrinsic opacity and higher roughness of regular paper greatly restricts further applications. One promising method is to use cellulose nanofibers (CNs) to fabricate nanopaper with a high optical t...
