The dielectric constant and its effects on the properties of a capacitor

source: Capacitor Faks blog A typical capacitor comprises two conductive plates and a non-conductive dielectric material. The dielectric material separates the two conductive metal electrode plates. Applying voltage to the electrode plates of a capacitor causes an electric field in the non-conductive dielectric material. This electric field stores energy. The dielectric constant, also commonly known […]

Critical Elements’ Countdown to Construction

source: Investor intel news 2017 hosted two major lithium milestones: the spot price rose to its highest ever levels, and the rate of growth was greater than in any other year; the race really is on to bring product to market in time for peak pricing. There are, of course, a number of lithium projects […]

Carbon Nanotubes Ammonia Sensor Printed by Aerosol Jet System

source: RICE, FEE, University of West Bohemia in Pilsen, EPCI e-Symposium Abstract: This article deals with ammonia gas sensor based on carbon nanotubes. Active layer is deposited on a flexible substrate by new deposition technique called Aerosol Jet. The deposition technique remove deficiency of today’s common used deposition technique, where it is very difficult to […]

An integration of electronic components and systems directly on/into textile substrates leads to the development of promising new technologies among which it is possible to include printing of passive electronic components and/or embroidering […]

Heraeus Next Generation of Polymer Capacitors: Boosting Performance of Electrolytic Capacitors with Conductive Polymer Dispersions

source: Heraeus, EPCI e-Symposium Abstract: The major use of polymer aluminum and tantalum capacitors is for low voltage consumer electronics. The development of conductive polymer dispersions has extended the voltage range of polymer capacitors up to 125 V in the last years and opened the door for high reliability applications like automotive. We present the […]

Project for Energy Storage on a Chip for MEMS

source: FEEC Brno University of Technology, EPCI e-Symposium Abstract: A new project with a budget of 262 thousands Euro was motivated by the lack of micromachined energy storage solutions that can be integrated with a MEMS harvester on a chip with a specific circuitry. These key components of the system are highly needed for autonomous […]

Researchers Develop Solid-State, Free-Standing Carbon Nanofiber Supercapacitor

source: PHYS.ORG news A group of Drexel University researchers have created a fabric-like material electrode that could help make energy storage devices—batteries and supercapacitors—faster and less susceptible to leaks or disastrous meltdowns. Their design for a new supercapacitor, which looks something like a furry sponge infused with gelatin, offers a unique alternative to the flammable […]
