A resistance between the first terminal and the second terminal includes a resistance of the on-thin-film layer pattern, a resistance between the third terminal and the fourth terminal includes the resistance of the on-thin-film layer pattern and a resistance of the on-substrate pattern, and the resistance between the first terminal and the second terminal is less than the resistance between the third terminal and the fourth terminal.

Provided is a sensing system that has a long life span. The sensing system includes a first detector (1) and a second detector (2) that detect at least one type of detection target which is included in a first concept which is common to both of detection targets, and which is included in a subordinate concept of the first concept; and a controller (3) that controls, according to a detected value from any one of the first detector (1) and the second detector (2), start, stop, or a detection condition of detection operations of the other detector.

A device for detecting moisture for an arrangement for monitoring an access to a patient for a system by which, via a flexible line, a liquid is fed to a patient and/or a liquid is fed out from the patient, and in particular for monitoring the vascular access in extra-corporeal blood treatment and particularly for monitoring a central venous catheter for acute dialysis includes at least a portion which can be deformed into a sleeve and placed around the circumference of the flexible line or of a connecting system. The portion in sleeve form has fastening means for fixing it in place in the position in which it surrounds the flexible line or the connecting system. The portion in sleeve form allows the device to be fastened quickly and securely to a flexible line or a connecting system.

The purpose of the present invention is to realize a dew point measurement in which the generation of dew condensation is directly detected and the detection can be performed without using any optical system. In particular, the purpose of the present invention is to realize a dew point measuring device that is compact and has a high sensitivity. According to one embodiment of the present invention, a sudden change in current values before and after the dew point is detected by detecting the dew condensation to detect a galvanic current that flows due to a water droplet attached onto a surface of an insulating substrate on which thin wires of dissimilar metals are juxtaposed, and by controlling the temperature on the surface of the substrate. In this way, the dew point measurement in which the dew point can be directly measured and a measurement with simple configuration and high accuracy can be performed can be realized.

A micromechanical moisture sensor device includes: a substrate having a front side and a rear side; an interdigital printed conductor track arrangement provided above and/or below the front side of the substrate; and a moisture-sensitive polymer layer situated above and in the gaps of the interdigital printed conductor track arrangement. The moisture-sensitive polymer layer extends below the front side into the substrate.

A wood monitoring system and method is disclosed for monitoring lumber characteristics (e.g., lumber moisture) in environments of extremely high and prolonged temperature and moisture, e.g., a kiln. The monitoring system and method includes: (a) Sensors (provided within lumber stacks), wherein such sensors are battery powered and wirelessly communicate measurements indicative of moisture content of the wood adjacent to and/or between metal plates provided in an electrical circuit with the sensors and the wood between the plates; (b) Computer implemented methods and systems for wireless communication that conserve sensor battery power such that the sensors can operate for, e.g., six months within extremely adverse temperature and moisture environmental variations; and (c) Computer implemented methods and systems for estimating moisture content with a wood/lumber stack, and for predicting such moisture content (e.g., as a substantially steady state within the wood) after drying completion.
