Abstract: A device, method, and system that allows the easy add on attachment of an applied-power sensor, assuring precise measurements over time, even in vibrating environments such as exercise environments. The device possesses structural qualities such that tightening the wrapping latch around a measured object/part presses a loaded spring between the object/part and the sensor, achieving and maintaining sufficient and constant contact, thus allowing continuously precise measuring. The device also includes a transmitter to transmit the measured data to an external data processing device and may include a processor to process the data before transmitting.

Abstract: A flow velocity detector for detecting a flow velocity of a fluid flowing through a flow passage is provided, the flow velocity detector including a flow passage-forming section which defines the flow passage; a stress light-emitting section which is arranged at the flow passage-forming section to receive a stress having a magnitude depending on the flow velocity of the fluid and which emits a light of which amount corresponds to a change of the received stress; and a light-receiving sensor which receives the light emitted by the stress light-emitting section. The flow velocity of the fluid is detected based on an amount of the light received by the light-receiving sensor to generate a detection signal. Accordingly, the structure is simple and small-sized, and the flow velocity of the fluid can be detected at low cost.

Abstract: The invention relates to optical devices for measuring pressure or force, comprising an electromagnetic radiation source, and a pressure membrane or a spiral spring which has a surface that at least partially reflects the electromagnetic rays of the electromagnetic radiation source. The inventive devices are especially characterized in that they allow, inter alia, measurement of even the slightest pressure changes of fluids and other flowable materials in the stationary and/or flowing state or even the slightest mechanical deformations on spiral springs. In order to do this, the rays of an electromagnetic radiation source are incident on the at least partially reflective surface of the pressure membrane or spiral spring. At least one section of a stationarily located body or of a stationarily located body having a reflective layer is disposed in the path of the reflected rays, upstream of a photodetector for said rays, and projects into said rays. A mechanical modification causes the reflected rays to be absorbed, diffracted, reflected again and/or split to a higher or lesser extent by the body.

Abstract: A magnetic nanocomposite device is described herein for a wide range of sensing applications. The device utilizes the permanent magnetic behavior of the nanowires to allow operation without the application of an additional magnetic field to magnetize the nanowires, which simplifies miniaturization and integration into microsystems. In5 addition, the nanocomposite benefits from the high elasticity and easy patterning of the polymer-based material, leading to a corrosion-resistant, flexible material that can be used to realize extreme sensitivity. In combination with magnetic sensor elements patterned underneath the nanocomposite, the nanocomposite device realizes highly sensitive and power efficient flexible artificial cilia sensors for flow measurement or tactile sensing.

Abstract: The aim of the invention is to determine a force (EK) exerted upon an elastic surface (OF). According to the invention, a spring (F), which is opposed to the force, exerts a counter force. A spring bar (FS) which is fixed to one end is rigidly connected to the spring or to the surface. In the event of the application of force, the other end produces a relative movement in relation to the sensor element (SE). The sensor element can be embodied in a simple manner as a magnetic coil, wherein the inside thereof displaces the end of the magnetic spring bar and the inductivity of the coil modifies.

Abstract: An ultrananocrystalline diamond (UNCD) element formed in a cantilever configuration is used in a highly sensitive, ultra-small sensor for measuring acceleration, shock, vibration and static pressure over a wide dynamic range. The cantilever UNCD element (16) may be used in combination with a single anode, with measurements made either optically (20) or by capacitance (34). In another embodiment, the cantilever UNCD element (78) is disposed between two anodes (80, 82), with DC voltages (V1, V2) applied to the two anodes. With a small AC modulated voltage (90) applied to the UNCD cantilever element and because of the symmetry of the applied voltage and the anode-cathode gap distance in the Fowler-Nordheim equation, any change in the anode voltage ratio V1/V2 required to maintain a specified current ratio precisely matches any displacement of the UNCD lever from equilibrium. By measuring changes in the anode voltage ratio required to maintain a specified current ratio, the deflection of the UNCD cantilever element can be precisely determined. By appropriately modulating the voltages applied between the UNCD cantilever and the two anodes, or limit electrodes, precise independent measurements of pressure, uniaxial acceleration, vibration and shock can be made.
