    摘要： The present invention relates to a micromechanical sensor for analyzing liquid samples and an array of such sensors. The invention also concerns a method for sensing liquid samples and the use of longitudinal bulk acoustic waves for analyzing liquid phase samples micromechanically. The sensor comprises a body and a planar wave guide portion spaced from the body. At least one electro-mechanical transducer element are used for excitation of longitudinal bulk acoustic waves to the wave guide portion in response to electrical actuation and for converting acoustic waves into electrical signals. The wave guide portion is provided with a sample-receiving zone onto which the sample can be introduced. By means of the invention, the sensitivity of micromechanical liquid sensors can be improved.

    摘要： This publication discloses a method and apparatus for functionalizing nanoparticle systems. The method comprises treating a nanoparticle-containing layer so as to produce a pattern of structurally transformed zones, the treatment comprising applying an electric field through the nanoparticle layer. According to the invention an AC-field capacitively coupled to the nanoparticle-containing layer is used as said electric field. The treatment preferably results in at least partly sintered structures, which can be used as conductors, for example. The document discloses several realizations for utilization of the disclosed functionalization in mass-fabrication lines.

    摘要： This publication concerns electronics modules comprising at least one first material zone formed of first material which can be structurally transformed by means of electric interaction in order to increase its conductivity at least locally, the first material having a first transformation threshold, and at least one second material zone in the vicinity of the first material zone. According to the invention, the second material zone is formed from second material, which can also be structurally transformed in order to increase its conductivity, the second material having a second transformation threshold, which is lower than the transformation threshold of the first material zone. With the aid of the invention, post-processing electrical programmability and non-volatility of printable memories can be achieved.
