The present disclosure is directed toward a method for aligning a radiation head of a terahertz sensor system with a target surface. The method includes: scanning a selected area of the target surface with a terahertz radiation beam emitted by the radiation head; sensing a peak amplitude for each reflected radiation signal from a plurality of reflected radiation signals received by the radiation head during the scanning of the selected area; and identifying a normal position of the radiation head with respect to the target surface based on a maximum peak amplitude from among the peak amplitudes of the reflected radiation signals.

The present invention regards nano surfaces and particularly a gradient based nano surface. According to embodiments of the invention a surface bound gradient is created by distributed nanoparticles along a plane surface. This procedure greatly reduces the number of prepared surfaces needed, as well as the methodological error of analysis of adsorption and adhesion phenomena.

In one example in accordance with the present disclosure a fluid property sensing device is described. The fluid property sensing device includes a substrate having a trench formed therein. The trench includes a bottom surface and opposite side surfaces. A first electrode is disposed on a first side surface of the trench and a second electrode is disposed on a second side surface of the trench. The first electrode and second electrode form a capacitor to measure a complex impedance of a fluid that fills a space between the first electrode and the second electrode. This complex impedance indicates a property of the fluid. A fluid level sensing die, having a number of fluid level sensing components disposed thereon, may be attached to the substrate, preferably in such a way that the fluid level sensing die is surrounded by the trench. In this way the surface area of the electrodes provided in the trench can be increased. The number of level sensing components may be thermal sensing components.
