An electrical energy storage device structure comprises a first conductive sheet, a second conductive sheet and an electrolyte sheet placed between the first conductive sheet and the second conductive sheet. In the device, at least one of the first conductive sheet and the second conductive sheet comprises a layer of carbon nanoparticles. The carbon nanoparticle layer is arranged to be adjacent to the electrolyte sheet. The carbon nanoparticles may include both high aspect ratio carbon nanoparticles and low aspect ratio carbon nanoparticles. The device is flexible and at least partially transparent.

Nano-structured flexible electrodes, and energy storage devices using the same

A capacitive sensor electrode for sensing a touch input. A material is configured to temporarily modify a capacitance of the capacitive sensor electrode during a period after a touch input has occurred. After the touch input has occurred, a material change in capacitance of the material is relatively slower than an electrode change in capacitance of the capacitive sensor electrode.

Apparatus and/or method for sensing touch input

An apparatus including polymer configured to have a first state or a second state, wherein the volume of the polymer in the first state is different to a volume of the polymer in the second state; an actuator configured to be controlled by an input signal to cause the polymer to change between the first state and the second state; and a constraint configured to constrain the polymer in at least a first direction when the polymer changes between the first state and the second state.

Apparatus that changes physical state and a method

A mixture including a room temperature ionic liquid; and a reversible source/sink of lithium ions. The mixture may be used as a lithium-ion battery electrode slurry enabling flexible lithium-ion batteries.

Mixture, a slurry for an electrode, a battery electrode, a battery and associated methods

An energy storage device structure comprises a first electrode layer, an electrolyte layer and a second electrode layer. At least one of the electrode layers comprise a metallic base layer, a layer of carbon nanotubes grown on the base layer and a layer of carbon nanoparticles disposed on the carbon nanotube layer, the carbon nanoparticle layer being arranged to face the electrolyte layer. The structure has much larger width and length than thickness, so it is rolled up or folded and then hermetically sealed to form an energy storage unit. The layer of carbon nanotubes is grown on the metallic base layer by a chemical vapor deposition process at a temperature no higher than 550&#xb0; C. The carbon nanotubes in the carbon nanotube layer are at least partially aligned in a direction that is perpendicular to the surface of the metallic base layer.

High efficiency energy conversion and storage systems using carbon nanostructured materials

An apparatus is disclosed that includes a first node coupleable to a power supply, a charge storage component coupled between a second node and a third node, and a first leg between the first node and second node. The first leg includes a first switching device. The apparatus includes a second leg between the first node and the third node. The second leg includes a second switching device. The apparatus includes a third leg between the second node and a fourth node. The third leg includes a third switching device. The apparatus includes a fourth leg between the third node and the fourth node, wherein the fourth leg includes a fourth switching device. The apparatus includes one or more contacts in one of the second leg or the third leg, the one or more contacts configured to be coupled to a load. Charging and load driving operations may be performed.

Drivers for loads such as light emitting diodes

A trap Including: an inlet configured to receive a fluid conveying nanostructures; ionic liquid configured to trap the nanostructures; and an outlet for the fluid.
