摘要:
A class of devices enabled by ionic conductors is highly stretchable, fully transparent to light of all colors, biocompatible or biodegradable, and capable of operation at frequencies beyond 10 kilohertz and voltages above 10 kilovolts. These devices enabled by ionic conductors can be used as large strain actuators, full-range loudspeakers, as strain or pressure sensors and as stretchable interconnects. The electromechanical transduction is achieved without electrochemical reaction. When large stretchability and high optical transmittance are required, the ionic conductors have lower sheet resistance than all existing electronic conductors.

摘要:
An electronic or electro-optic device has a first electrode, a second electrode spaced apart from the first electrode, and a dielectric layer disposed between the first and second electrodes. The dielectric layer has electrically insulating planar layers with intercalated ions therebetween such that the electrically insulating planar layers provide a barrier to impede movement of the intercalated ions to the first and second electrodes under an applied voltage while permitting a polarization of the dielectric layer while in operation.

摘要:
An electrolyte solution for driving an electrolytic capacitor having a solvent composed of 20 to 80 wt % of an organic solvent and 80 to 20 wt % of water, characterized in that it comprises one or more nitro compounds or nitroso compounds exclusive of nitrophenol, nitrobenzoic acid, dinitrobenzoic acid, nitroacetophenone and nitroanisole an electrolytic capacitor commprising the electrolyte solution for driving an electrolytic capacitor and an electrolytic capacitor comprising one or more nitro compounds or nitroso compounds located at another portion than an electrolyte solution therein. The electrolyte solution preferably contains a carboxylic acid or a salt thereof or an inorganic acid or a salt thereof as an electrolyte. The electrolytic capacitor exhibits a low impedance, excellent low temperature characteristics and good life characteristics, and further, is excellent in the effect to absorb a hydrogen gas, even when use is made of an electrolyte solution employing a mixed solvent having a great water content and when an electrolytic capacitor is used under a high temperature condition.
