A self-powered sensing system is provided for the monitoring of quasi-static structural responses. The sensing system is comprised of: an energy concentrator having a member configured to detect a variation of a physical stimuli and change shape in response to the variation of the physical stimuli, where the variation typically occurs at a frequency less than one Hertz; a transducer coupled the member of the energy concentrator and generates a voltage in response to the change in shape of the member; and an event logging circuit configured to receive the voltage from the transducer and log the voltage in a non-volatile memory. Physical stimuli may include temperature, pressure or an applied force.

A method for producing a sensor on the surface of a functional layer, in which suitable sensor material in the form of powder or a wire is melted in a laser beam by way of a method similar to laser cladding and subsequently is applied to the surface of the functional layer. There is provided a considerably improved method for producing sensors, and in particular in-situ sensors, wherein the sensors can also be deposited onto a functional layer that, in part, is very coarse, without having to employ complex masks, as has previously been customary. The ease of adapting the method parameters ensures broad use both with respect to the sensor to be produced and the functional layer to be detected. The sensors thus produced are used, in particular, to detect components that are subject to high temperatures or the functional layers thereof. The sensors that can be produced in accordance with the invention include, in particular, temperature, pressure or voltage sensors, as well as acceleration sensors.

A sensor connector compatible with various sensor unit repertoires and capable of improving production efficiency is provided. The sensor connector includes terminal modules to be inserted into a module inserted portion, and commonized pogo pin type terminal module is brought into contact with a connection terminal via slide contact segments capable of sliding relative to the connection terminal exposed to a region closer to the module inserted portion. Thus, the sensor connector can be compatible with the sensor unit 1 having various repertoires by changing, for example, the arrangement and the number of poles of the module inserted portions of the connector housing.
