There is growing interest in thin, lightweight, and flexible energy storage devices to meet the special needs for next-generation, high-performance, flexible electronics. Here we report a thin, lightweight, and flexible lithium ion battery made from graphene foam, a three-dimensional, flexible, and conductive interconnected network, as a current collector, loaded with Li(4)Ti(5)O(12) and LiFePO...

A tactile sensor system, based upon the electric field distortion, is proposed. Tactile sensors, detecting electric resistance or capacitance, have two opposing electrodes in general. Such structure have difficulty to make flexible sensor sheet, which is needed for robotic manipulator or other skin like sensing purpose. In this study, a sensing system with one electrode, embedded in conducting ...

For suppressing the crosstalk problem due to wire resistances and contacted resistances of the long flexible cables in tactile sensing systems, we present a novel two-wire fast readout approach for the two-dimensional resistive sensor array in shared row-column fashion. In the approach, two wires are used for every driving electrode and every sampling electrode in the resistive sensor array. Th...

CONCLUSIONS The present experimental set-up of high spatial resolution cone-beam computed tomography (CBCT) showed advantages of demonstrating the critical landmarks of the cochlea in identifying the position of intracochlear electrode contacts and has the potential for clinical application in cochlear implant (CI) surgery. OBJECTIVE To evaluate a newly developed CBCT system in defining CI el...

PURPOSE To develop a liquid crystal polymer (LCP)-based, long-term implantable, retinal stimulation microelectrode array using a novel fabrication method. METHODS The fabrication process used laser micromachining and customized thermal-press bonding to produce LCP-based microelectrode arrays. To evaluate the fabrication process and the resultant electrode arrays, in vitro reliability tests an...

Here we construct mechanically flexible and optically transparent thin film solid state supercapacitors by assembling nano-engineered carbon electrodes, prepared in porous templates, with morphology of interconnected arrays of complex shapes and porosity. The highly textured graphitic films act as electrode and current collector and integrated with solid polymer electrolyte, function as thin fi...

Meandering beams, crenellated surfaces, and zigzag-shaped electrodes are employed as compliant elements in micro-scale applications ranging from springs attached to proof masses in micro-electro-mechanical systems (MEMS) to stretchable electrodes in flexible electronics and dielectric elastomer actuators. An understanding of how the meander shape affects the stiffness of these structures would ...

Considerable research and development means have been focused in the past decade on organic semiconductor thin films and devices with applications to full color displays, flexible electronics and photovoltaics. Critical areas of these thin films are their interfaces with electrodes, with other organic films and with dielectrics, as these interfaces control charge injection and transport through...

In order to restore hand function in spinal cord injured people by functional electrical stimnlation of arm nerves, we developed an lllpolar neural cuff type electrode with integrated multiplexer circuit. This circuit reduces the number of necessary interconnection leads to a stimulator from twelve to four. Cable reduction was intended to reduce the risk of cable breakage which is one of the ma...

An organic thiolate/disulfide redox couple with low absorption in the visible region was developed for use in fabricating novel dye-sensitized photovoltaic wires with an aligned carbon nanotube (CNT) fiber as the counter electrode. These flexible wire devices achieved a maximal energy conversion efficiency of 7.33%, much higher than the value of 5.97% for the conventional I(-)/I3(-) redox coupl...
