    Abstract: The present invention relates to the use of acoustic waves for the manipulation and sorting of particles and cells. In an embodiment, there is provided a microfluidic device for manipulating a particle in a fluid suspension, the device comprising: (a) a substrate; (b) a channel defined in the substrate, the channel having an inlet for receiving the fluid suspension and an outlet for discharging the fluid suspension; and (c) an acoustic source configured to deliver a travelling surface acoustic wave transverse the flow of the fluid suspension in the channel, wherein the acoustic source is an interdigital transducer (IDT), the IDT comprises a plurality of concentric circular arcs having a tapered end directed at the channel, and the tapered end has an aperture of between 4 μm and 150 μm. In an alternative embodiment, the device comprises a second channel disposed intermediate the first channel and the acoustic source wherein the first and second channels are connected by a pumping channel.

    Abstract: A tectonic origami device (100) is disclosed, which includes a flexible supporting substrate (102); and a plurality of substantially rigid planar members (104) arranged on the supporting substrate, the planar members configured in a non-overlapping cooperative arrangement to permit assembly of the device to form an enclosure. The device is configured to be transformable between a collapsed form where the supporting substrate and planar members are collectively in a planar arrangement and an assembled form where the supporting substrate and planar members are collectively assembled as the enclosure.

    Abstract: The present invention relates to nanofibers. In particular, the present invention relates to potassium niobate nanofibers. In an aspect of the present invention, there is provided a method of preparing the nanofibers, the method comprising: (a) dissolving niobium chloride and potassium sorbate in a solvent to obtain a first solution; (b) removing chloride precipitates formed from the first solution; (c) adding a polymer, for example polymethylmethacrylate or polyvinylpyrrolidone to the solution to obtain a second spinnable solution; and (d) electrospinning the spinnable solution to produce the fibers. The application also discloses the application of such nanofibers in the manufacture of a humidity sensor device by sputtering a metal such as Tantalum on top of the nanofibers.

    Abstract: The present invention relates to a magnetic levitator. The magnetic levitator comprises a first portion having a first arrangement of a plurality of permanent magnets, and the first arrangement has first and second circumferences. The magnetic levitator also comprises a second portion having a second arrangement of a plurality of permanent magnets, and the second arrangement has a third circumference. The first and second arrangements are rotationally symmetrical, and the first circumference is larger than the third circumference. In use, one of the portions is magnetically levitated by the other one of the portions, and the second circumference is arranged substantially aligned to the third circumference.
