Abstract: A Microelectromechanical systems (MEMS) based ring resonator includes an outer ring which is supported in resilient deformable movement relative to one or more peripherally disposed electrodes by a symmetrically positioned array of radially extending inner spring supports. The inner spring supports extend radially from a central anchor post or support to the inner circumferential edge of the outer ring. The innerspring supports are configured to deformation or regulate movement in outer ring driving and sensing modes.

Abstract: In a preferred embodiment, there is provided a self-healing polymer composition preferably for use in manufacturing a dielectric layer of a capacitive pressure sensor, and which comprises a central atom and a polymer having a main chain and one or more terminal moieties coupled to the main chain, wherein said one or more terminal moieties are selected to operate as ligands to form a coordination complex with the central atom, and preferably, the ligands and the central atom are selected to form the coordination complex after being subject to an external force sufficient to remove coordinate covalent bonds therebetween.

Abstract: In a preferred embodiment, there is provided a method for preparing a capacitive pressure sensor, the sensor comprising a pair of conductive plate layers and a dielectric layer disposed therebetween, the dielectric layer comprising a dielectric polymer formed with a polymerization mixture fluid, wherein the method comprises placing the polymerization mixture fluid over a mold surface having a first three dimensional pattern thereon to form the dielectric polymer, thereby forming a second three dimensional pattern on a surface of the dielectric polymer complementary to the first three dimensional pattern.

Abstract: There is described herein methods and devices for confining and/or manipulating molecules. At least one molecule is introduced into a fluidic chamber. The fluidic chamber is formed inside a device comprising at least one first electrode having a first surface spaced from at least one second electrode having a second surface facing the first surface. The at least one second electrode has a plurality of dielectric structures arranged to form openings along the second surface. At least one electrical signal is applied across the at least one first electrode and the at least one second electrode to generate a non-uniform electric field having electric field lines extending from the first surface of the at least one first electrode to the second surface of the at least one second electrode in the openings formed between the dielectric structures. The at least one electrical signal has a frequency level causing the at least one molecule to move inside the fluidic chamber in accordance with a predetermined movement.
