A metal hydride (MH) actuator provides mechanical work by applying the hydrogen pressure transition that originates from the reversible reaction of the MH alloy as it absorbs and desorbs hydrogen gas. The MH actuators that have been reported employ a Peltier element or an electrical heating resistance wire as a heat source. This paper describes the design of an MH actuator that is driven by low-quality...
Organic photo-diodes based on various J-aggregated cyanine dyes, NK-3989, NK-1952 and NK-2203 doped into conductive polymer films patterned by ink-jet method on ITO substrates have been obtained. Wavelength sensitivity has been observed from the photo-diodes.
In this paper, the fabrication of organic photo-diodes based on various J-aggregated cyanine dyes doped into PEDOT:PSS films by ink-jet is demonstrated and the properties especially the wavelength sensitivity of the photo-diodes have been investigated.
A metal hydride (MH) actuator that uses the reversible reaction between the heat energy and mechanical energy of a hydrogen absorbing alloy is characterized by its small size, low weight, noiseless operation and mechanical compliance. Though the moving speed of the MH actuator is slow, this actuator is a suitable as a power source for rehabilitation or assistive devices. Prototype assistive devices...
