Scaffolds that couple electrical and elastic properties may be valuable for cardiac cell function. However, existing conductive materials do not mimic physiological properties. We prepared and characterized a tunable, hybrid hydrogel scaffold based on Au nanoparticles homogeneously synthesized throughout a polymer templated gel. Conductive gels had Young's moduli more similar to myocardium rela...

An electronic system was designed to acquire tunneling current of a Scanning Tunneling Microscope. A tunneling current originates from the interaction between a conductive tip and a conductive or semiconductor sample. Lower currents than 100 nA were generated and from them, voltages were obtained in the order of 1 volt. Using this mechanism, it is possible to construct images of the atoms posit...

With the phasing out of lead-bearing solders, electrically conductive adhesives (ECAs) have been identified as one of the environmentally friendly alternatives to tin/lead (Sn/Pb) solders in electronics packaging applications. In particular, with the requirements for fine-pitch and high-performance interconnects in advanced packaging, nanoconductive adhesives are becoming more and more importan...

The developed analytical model refers to an electromagnetic device intended for sorting conductive materials, as in the waste management domain. The main component of the device is a probe coil with ferrite open core that has to be placed near the piece of conductive material subject to sorting. When the probe coil is supplied by a mean frequency voltage source, eddy currents are induced into t...

The focus of this paper is to make a comparison between five different types of conductive, heatable samples. These textile samples have been produced according to the five most important implementation techniques such as knitting, weaving, embroidery, printing and nonwoven padding. The idea is to identify a conductive option best suitable for a heating application. This study was divided into ...

Conductive films that are both stretchable and flexible could have applications in electronic devices, sensors, actuators and speakers. A substantial amount of research has been carried out on conductive polymer composites, metal electrode-integrated rubber substrates and materials based on carbon nanotubes and graphene. Here we present highly conductive, printable and stretchable hybrid compos...

Electrode used in lithium-ion battery is invariably a composite of multifunctional components. The performance of the electrode is controlled by the interactive function of all components at mesoscale. Fundamental understanding of mesoscale phenomenon sets the basis for innovative designing of new materials. Here we report the achievement and origin of a significant performance enhancement of e...

Microwave imaging problem consists of reconstructing unknown objects from measurements of the scattered field that results from their interaction with a known interrogating wave. This problem is nonlinear and ill-posed. The most classical methods to solve this inverse problem are based on the linearization of the model (by using Born or Rytov approximation) or work directly on the nonlinear map...

Electrically conductive composite materials can be used for a wide range of applications because they combine the advantages of a specific polymeric material (e.g., thermal and mechanical properties) with the electrical properties of conductive filler particles. However, the overall electrical behaviour of these composite materials is usually much below the potential of the conductive fillers, ...
