摘要： The design and deposition of a sensing layer for room temperature SAW/BAW chemical sensors utilizing macrocyclic compounds in accordance with supra-molecular chemistry principles. The gas to be sensed is attached to the organic sensing film thus changing its visco-elastic properties and creating a mass increase of the film deposited on the surface of SAW/BAW devices. A direct printing method can be used as an additive, mask-less procedure to deposit metallic interdigital transducers and electrodes required for SAW/BAW devices, along with the deposition of a guiding layer and the organic films only on the location required by the sensing SAW/BAW principle of the sensor. Different thermal treatment solutions can be used for the consolidation of the gelly organic films deposited by the direct printing methods.

摘要： Methods can be adapted for design of a sensitive monolayer for detection of hydrogen sulphide at room temperature with SAW/BAW devices. The sensitive monolayer can be synthesized based on chemical compounds, which belongs to a class of thiacalix[n]arenas, mercapto halides, mercapto alcohols and chloromethylated thiacalix[n]arenas. The sensitive monolayer can be directly immobilized or anchored at the surface of a piezoelectric quartz substrate in a covalently bonded manner by means of direct printing process. The piezoelectric quartz substrate can be activated in basic medium or in acid medium before the immobilization of the sensitive monolayer in order to increase the population of OH groups. Thus, the synthesized sensitive monolayer exhibits a high site density, fast response and long-term stability for H2S sensing.

摘要： A multifunctional multichip system can operate in a passive mode by using at least one antenna to receive electromagnetic energy and using that energy to perform system functions. The system includes a sensor, an impedance matching circuit and an RFID module. The sensor produces a sensor signal containing a measurement. The RFID can produce an identification signal containing identification information. Alternatively, the RFID chip can be used in an addressing mode wherein the system only produces a signal in response to an addressing signal containing addressing information. The addressing signal is received from the electromagnetic field. In either mode, the sensor signal is coupled from the antenna into the electromagnetic field from which a receiver can obtain it. The signal can contain the identification information as well as the measurement. A matching network minimizes the effects of impedance mismatches between the system elements.

In some instances, a solar cell may include a tunable electron conductor that permits greater choices in quantum dots, thereby providing solar cells that can be constructed to utilize a larger fraction of the solar spectrum. In some cases, the electron conductor may include group III nitride-based materials. A solar cell assembly is also disclosed that may include a first quantum dot solar cell and a second quantum dot solar cell. The first and second quantum dot solar cells may be tuned for differing portions of the electromagnetic spectrum.

摘要： A method can be adapted for design and preparation of a matrix nanocomposite sensing film for hydrogen sulphide SAW/BAW detection at room temperature. A matrix nanocomposite can be synthesized by incorporating both single-wall and multi-wall thiolated carbon nanotubes into conductive organic polymers or ceramic nanocrystalline in a properly functionalized manner. A thin organic sensing film can be prepared based on the matrix nanocomposite. The matrix nanocomposite sensing film can be prepared on a surface of a SAW/BAW device by an additive process or a direct printing process. Finally, the sensing film can be consolidated by thermal annealing or laser annealing under ambient conditions in order to obtain the stable sensing film with higher sensitivity and electrical properties for a SAW/BAW based H2S sensor.
