Current wearable technology is often bulky and restrictive to fluid movement. This work details a single-layer, hydrophobic, printed electrochromic textile that switches wirelessly from red to blue with a switching speed ≈30 s. Using a hole-through fabrication method, the flexible devices offer aesthetics to the display by concealing all electronic...

Herein, screen printed electrodes prepared from commercially available conducting polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate have been shown to record simultaneous electromyogram (EMG), electrocardiogram (ECG), and electrodermal activity (EDA) from a spandex t-shirt sleeve in dry state. Secondly, electrodes printed on an arm sle...

High‐performance flexible loudspeakers have the potential to revolutionize the future of flexible/wearable electronics by providing this long‐sought function. Here, a novel method is developed to produce large‐area, flexible, and transparent piezoelectric loudspeakers, where both piezoelectric lead zirconate titanate (PZT) nanoparticles and graphen...

The next-generation wearable system calls for flexible, breathable, and skin-friendly wireless transmitters for realizing the body area network and the Internet of Things. This work presents the first fully functional, poly (3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) screen-printed fabric patch antenna for next-generation wearab...

Highly conductive, metal-like poly(ethylene terephthalate) (PET) nonwoven fabric was prepared by coating poly(3,4-ethylenedioxythiophene): poly(4-styrene sulfonate) (PEDOT:PSS) containing dimethylsulfoxide (DMSO) onto PET nonwoven fabric previously coated with graphene/graphite. The sheet resistance of the original nonwoven fabric decreases from >8...

Herein, the fabrication of all organic conductive wires is demonstrated by utilizing patterning techniques such as inkjet printing and sponge stencil to apply poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) onto nonwoven polyethylene terephthalate (PET) fabric. The coating of the conducting polymer is only present on the surface...

Higher filler loading in incompatible polymer blends generally leads to catastrophic deterioration of physico-mechanical properties. This investigation reports effect of an elastomeric compatibili-zer on the mechanical properties of carbon black (CB) filled immiscible Polypropylene (PP)/Low density polyethylene (PE) blends. The composites were prep...

This article reports exceptional synergistic effects observed in organic inorganic dual filler containing ethylene vinyl acetate (EVA) composites. Polytetrafluoroethylene microparticles (PTFEMP) were produced by mechanically grinding radiolytically degraded PTFE; composites of EVA containing PTFEMP and organoclay were prepared in different proporti...

Unusual electrical conductivity was demonstrated by ethylene vinyl acetate/polycaprolactam/carbon black (CB) composites. The critical exponent value was 1.2 ± 0.2 for ternary composites and was greater than 2.0 for the binary composites, indicating two-dimensional electrical conduction in ternary composites. The ternary composites also showed inver...
