Method and Systems for extracting a concentrated sample of particles include priming a concentrate reservoir by passing a fluid through the concentrate reservoir to remove air. The concentrate reservoir has a first end with an opening and second end with an opening. The second end of the concentrate reservoir is closed off, and particles are accumulated within the concentrate reservoir by use of a particle concentrator. Thereafter, the first end of the concentrate reservoir is closed off, isolating the concentrate reservoir from particle concentrator, from which the particles were obtained. The second end of the concentrate reservoir is thereafter opened, and the particles of the concentrated sample in the concentrate reservoir are extracted to a sample capture reservoir through the second end opening of the concentrate reservoir.

A fluidic system and method includes a channel reservoir which holds 1.5 milliliters or less of fluid. The agitation mechanism, which is partially integrated with the channel or reservoir, includes a fiber or rod at least partially situated within the channel or reservoir, and which acts to move or vibrate to stir and/or agitate fluid within the channel or reservoir. The fluid is then extracted from an extraction area following the agitation or stirring operation.

According to one embodiment, a method of forming a solar energy converter assembly disclosed herein includes providing a solar energy converter configured to convert light incident on a light-receiving surface thereof into another form of energy and providing louver elements adjacent to the light-receiving surface such that light is transmittable between the louver elements to the light-receiving surface along a plurality of directions. Display surfaces of the louver elements are visible along a predetermined direction different from the plurality of directions and non-display surfaces of the louver elements reflect light to the light-receiving surface.

An interactive card or the like employs a piezoelectric charge generator (piezo-strip) for temporarily driving an indicator. The piezo-strip may be displaced (bent) in order to generate charge to drive the indicator. Printed electronic processes are utilized to produce the indicator and/or the piezoelectric charge generator The need for a printed battery or supplemental power source is obviated. The card may carry printed indicia which corresponds to the states of the indicator (e.g., indication of a test answer selection). Multiple display elements and selector switches may provide multiple indicator states. Multiple piezo-strips may provide a selection function as well as a rest function. Applications include business cards, greeting cards and novelty items, toys and games, advertising and promotions, testing and education, sensors, and so forth.

A device has a substrate, a piezo polymer layer arranged adjacent the substrate, a first electrode in contact with a first side of the layer, and a second electrode arranged adjacent the first electrode, such that when the piezo layer flexes, the first and second electrodes are arranged to detect one of a change in voltage or resistance, wherein at least one of the piezo polymer layer or the electrodes are deposited by printing. A method including depositing a spacer layer onto a substrate, depositing a piezo polymer layer onto the substrate, patterning an array of first electrodes in contact with the piezo polymer layer, and patterning an array of second electrodes adjacent the array of first electrodes, wherein depositing includes one of printing and laminating and pattering includes one of printing and etching. A method including laminating a piezo polymer layer onto a substrate, such that the layer forms at least one cantilever beam, forming a first electrode on one side of the layer, arranging a second electrode adjacent the first electrode, printing a polymer layer on the cantilever beam, and printing a proof mass on the cantilever beam.
