Abstract Commercial thermally conductive dielectric materials used in electronic packaging typically exhibit thermal conductivities ( κ ) ranging from 0.8 to 4.2 W m −1 K . Hexagonal boron nitride (h‐BN) flakes are promising for the management of next‐generation electronics. These electrically insulating yet conducting h‐BN can be incorporated as fillers impart high polymer‐based composites. A cellulose‐based composite embedded with few‐layer (FLh‐BN) flakes, achieving a ≈ 21.7 , prepared...
Abstract Continuous monitoring of biomarkers in interstitial fluid (ISF) holds great potential for early disease detection and personalized medicine.
This work presents a novel biosensing platform that combines microneedle technology with graphene field-effect transistors (GFETs) to
enable sensitive, continuous analyte directly ISF. Using spray-coating laser lithography techniques, we create GFET
channels on three-dimensional tips. The resulting devices show...
Abstract Textile‐based energy storage components are paramount for establishing invisible electronic textiles that do not require conventional rigid batteries. A novel and scalable fabrication method is reported introducing MXene (Ti 3 C 2 T x ) into activated carbon (AC) supercapacitors to enhance electrochemical performance. Supercapacitors prepared within a single layer of textile with phase‐inverted polymer membrane fabricated the yarn structure form porous, flexible, mechanically...
Metallic MXenes are promising two-dimensional materials for energy storage, (opto)electronics, and photonics due to their high electrical conductivity strong light-matter interaction. Energy dissipation in is fundamental photovoltaic photothermal applications. Here we apply ultrafast laser spectroscopy across a broad time range (femto- microseconds) study the cooling dynamics of electrons lattice emerging Ti
Small band gap molecular semiconductors are of interest for the development transparent electronics. Here we report two near-infrared (NIR), n-type small molecule semiconductors, based upon an acceptor–donor–acceptor (A-D-A) approach. We show that inclusion spacers between strong-electron-accepting end group, 2,1,3-benzothiadiazole-4,5,6-tricarbonitrile, and donor core affords with very low gaps down to 1 eV. Both materials were synthesized by a one-pot, 6-fold nucleophilic displacement...
Lab-on-printed circuit board platform for scalable electrochemically-gated graphene field effect transistors test strips, measuring pH and Na + ion concentration.
Graphene field effect transistors (GFETs) are promising devices for biochemical sensing. Integrating GFETs onto complex non-planar surfaces could uncap their potential in emerging areas of wearable electronics, such as smart contact lenses and microneedle However, the fabrication on is challenging using conventional lithography approaches. Here, we develop a combined spray-coating photolithography setup scalable demonstrate application integrated microneedles. We optimize to pattern ∼ 67 μm...
