A product [11] includes a foldable clamshell-type housing [10] folded to a closed position to contain a pre-formed sensor pad [17] that was formed in situ therein when the housing [10] was in an open position, prior to closing. The housing [10] has an enclosed volume [12] bounded by relatively thin and flexible walls [23, 34], and outwardly extending tabs [18] which facilitate opening. This structure enables the user to easily open the housing [10] to remove the sensor pad [17], a cured silicone composition, by pushing inward on an outer surface of the outer wall [34] of a base section [15] of the housing [10]. This product [11] reduces the amount of manipulation needed to place the sensor pad [17] in a desired position, for example, during installation of a rain sensor system for a vehicle windshield.

A sensor module contains a sensor unit, a sensor cover, and a main body. The sensor unit has a sensor surface and a base surface. The sensor cover covers the sensor surface and at least a section of the base surface. The sensor cover is connected to the base surface and/or the main body by a fused connection. The main body is connected at least to the base surface of the sensor unit by a fused connection with a selectable relative position in relation to the sensor cover. Pre-mounting of the sensor unit in a sensor cover and advantageous encapsulation of a sensor can thus be achieved.

An electrode with varying impedances includes a plurality of layers that are compressed together with varying compressions forces. A first compression force is used at the perimeter of the electrode and a second compression force is used towards the center of the electrode. The first compression force at the perimeter is lesser than the second compression force towards the center and creates a greater measured impedance at the perimeter of the electrode than at the center of the electrode.

A method of assembly includes providing a sensor having an electronic sensing unit operable to emit or receive light rays and a clear substrate attached to the electronic sensing unit. The method also includes providing a tubular protective wrap having a central orifice. The protective wrap has a transparent film layer and an interstitial layer. The interstitial layer is disposed on an interior surface of the film layer proximate the orifice. The method additionally includes disposing the protective wrap about the electronic sensing unit. The method further includes shrinking the protective wrap via application of heat such that the interstitial layer contacts at least a portion of the sensor with the film layer superposed over at least a portion of the clear substrate.

Provided are a method of producing a nanoparticle device and a nanoparticle device. The method of producing a nanoparticle device may be economical due to use of a hydrogel, may be easy to design in terms of mass production processes, and may reduce manufacturing times to 1/100 to 1/10 of the technology of the related art. In addition, a nanoparticle device may be produced in various designs by stably realizing a 3D pattern and pattern stacking, and may have highly uniform nanoparticle dispersion and excellent electrical activity through the removal of a surfactant without damaging the pattern. The nanoparticle device produced according to the production method may have excellent electrical activity due to nanoparticle uniformity pattern accuracy and thus may be applied to pattern stacking which could not be implemented by methods of the related art.

Described herein are various embodiments directed to rotor devices, methods, and systems. Embodiments of rotors disclosed herein may be used to characterize one or more analytes of a fluid. A method may include bonding a first layer and a second layer using two-shot injection molding. The first layer coupled to the second layer may collectively define a set of wells. The first layer may be substantially transparent. The second layer may define a channel. The second layer may be substantially absorbent to infrared radiation. A third layer may be bonded to the second layer using infrared radiation. The third layer may define an opening configured to receive a fluid. The third layer may be substantially transparent. The channel may establish a fluid communication path between the opening and the set of wells.

A microneedle biosensor includes a microneedle and a substrate. One end of the microneedle is connected to the substrate, an outer surface of the microneedle is provided with a working electrode and a first electrode, an outer surface of the working electrode is provided with an enzyme, and an outer surface of the microneedle biosensor is covered with a biocompatible film.

The substrate, the microneedle, the working electrode, the first electrode, the enzyme and the biocompatible film are all manufactured through a full printing method.

A universal sensor fabrication approach, molecular substrate imprinting technique, which utilizes the interaction between molecular building blocks and the surface of a transducer to develop specific molecular recognition cavities has been established. Integration of molecular recognition cavities with the surface of a nanoscale transducer will result in a nano-tunneling effect that takes place which will provide a sensor or a device that exhibits new properties not already exhibited by either the molecular recognition cavities on a bulk transducer or the nanotransducer material. One of the new properties of this nano-tunneling effect is that a universal potentiometric molecular sensor can be fabricated and used to detect any compounds, whether they are ions or molecules, with enhanced selectivity, sensitivity, and stability when molecular recognition cavities or elements are integrated on the surface of a nanoscale transducer.

Replaceable shaving assemblies are disclosed that include a blade unit, an interface element configured to removeably connect the blade unit to a handle, on which the blade unit is pivotably mounted, and a return element disposed between the blade unit and interface element. The return element serves as interface piece, connector and pivot all in one. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

A soft-melted parison is disposed in molds forming a shape of a measurement pipeline portion 10, the parison is expanded by means of gas inflow, and blow molding is performed. The shapes of a pipe body 11, a fluid inlet portion 12, and a fluid outlet portion 13 are formed by an inner mold of the molds. Ultrasonic wave input-output portions 14a and 14b bulging outwards in a sealed manner are formed on both sides positioned in the oblique direction of the pipe body 11 with respect to a center line of the pipe body 11. Parts of the ultrasonic wave input-output portions 14a and 14b are wall surfaces 15a and 15b for attaching ultrasonic wave transmission-reception units. The measurement pipeline portion 10 is obtained by cutting end portions of the fluid inlet portion 12 and the fluid outlet portion 13 after the parison is solidified.
