A flexible electronic device includes a flexible electronic circuit and a flexible microfluidic sensor homogeneously integrated into the flexible circuit. The flexible sensor includes a flexible microfluidic structure, a first material, a second material, and an electrode arrangement. At least one of the first and second materials is a fluid. The structure defines at least one microfluidic chamber. The first and second materials are disposed in the chamber. The second material has a physical property and an electrical property different from the first material. The electrode arrangement includes at least one pair of electrodes spaced apart from each other with at least a portion of the at least one chamber located functionally directly therebetween such that at least one electronic property measured across the pair is based on a relationship between the second material and the electrode pair. The relationship is based on a physical condition of the microfluidic structure.

A hybrid MEMS microfluidic gyroscope is disclosed. The hybrid MEMS microfluidic gyroscope may include a micro-machined base enclosure having a top fluid enclosure, a fluid sensing enclosure and a bottom fluid enclosure. The hybrid MEMS microfluidic gyroscope may include a plurality of cantilevers disposed within the bottom semi-circular portion of the micro-machined base enclosure or a single membrane disposed within the bottom semi-circular portion of the micro-machined base enclosure.

An acceleration sensor, a display device, a detecting system and a detecting method are provided; the acceleration sensor includes two electrodes arranged opposite to and insulated from each other, and a cavity arranged between the two electrodes; a liquid layer is arranged in the cavity, and the liquid layer occupies a portion of internal space of the cavity. A display device integrated with the acceleration sensor has advantages such as high degree of integration, compact structure and low production cost and so on.

Techniques are described herein that perform pressure sensing using pressure sensor(s) that include deformable pressure vessel(s). A pressure vessel is an object that has a cross section that defines a void. A deformable pressure vessel is a pressure vessel that has at least one curved portion that is configured to structurally deform (e.g., bend, shear, elongate, etc.) based on a pressure difference between a cavity pressure in a cavity in which at least a portion of the pressure vessel is suspended and a vessel pressure in the pressure vessel.

A sensing device includes a housing and at least one film extending across the housing. The at least one film divides the housing into a first compartment and a second compartment. At least one mass is disposed within the first compartment. The at least one mass id sized to rupture the at least one film. A fluid having a first color is disposed in the first compartment and a fluid having a second color is disposed in the second compartment.
