System and method for interactive distribution of digital content

The invention concerns a method of removing encapsulating material from encapsulated particles deposited onto a substrate. According to the method, a substrate is used which is capable of facilitating said removal of encapsulating material. The particles may be nanoparticles. In particular, the substrate-facilitated removal may result in sintering of the particles. The invention provides a novel way of functionalizing electronic structures using particulate matter and for conveniently producing e.g. printed electronics devices.

Described herein is a passive wireless resonating non-linear sensor that is typically based on a ferroelectric varactor. The sensor replies its data at an intermodulation frequency when a reader device illuminates it at two closely-located frequencies. Furthermore, described herein is a general intermodulation read-out principle for passive wireless sensors. A sensor utilizes a mixing element, such as a varactor and it can be equipped with a capacitive, inductive, or resistive sensor element. When the sensor is illuminated with signals with two frequencies it replies the sensor data at an intermodulation frequency.

The invention describes a manufacturing method for an acoustic balanced-unbalanced (balun) or balanced-balanced thin-film BAW filter based on lateral acoustic coupling. In laterally acoustically coupled thin-film BAW filters (LBAW) one can realize transformation from unbalanced to balanced electric signal if the electrodes of the balanced port are placed on the opposite sides of the piezoelectric film. The manufacturing process is simpler than in the corresponding component based on vertical acoustical coupling. The device can also realize impedance transformation.
