Abstract: An object of the present invention is to detect ammonia with high sensitivity and high selectivity using a nanomechanical sensor with a structure that is as simple as possible. A method for detecting ammonia according to an embodiment of the present invention comprises supplying a sample gas possibly containing ammonia to a nanomechanical sensor that detects a stress or a displacement using poly(methyl vinyl ether-alt-maleic anhydride) as a material of a receptor layer, and detecting presence or absence of ammonia or a content of ammonia in the sample gas based on an output signal from the nanomechanical sensor, in which the sample gas is a humidified sample gas with controlled relative humidity.

Abstract: Described herein are methods for forming resistive heaters and force sensing elements on a flexible substrate, and devices that include these elements to provide a force responsive conductive heater, such as a seat heater in a vehicle. The methods include printing a conductive ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The conductive inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material.

Abstract: A deformable sensor arrangement includes a deformable sensor attachable to a curved surface. The deformable sensor includes an elastic layer having a Young's modulus at least 0.01 MPa and a first yield strain at least 10%. A first stretchable electrode attaches to the elastic layer, and a stretchable electrically conductive wiring. The first stretchable electrode and the stretchable electrically conductive wiring stretch at least 5% without breaking. An electronic arrangement electrically couples to the first stretchable electrode via the stretchable electrically conductive wiring and obtains a first signal from the first stretchable electrode. An analyzer determines a calibrated value based on the obtained first signal and assembly compensation coefficients, which are based on material compensation coefficients, and a measured signal of the deformable sensor in its installing position. A system and method are for installing the arrangement. A method and computer program determine a value of interest.
