摘要： The disclosure relates to wireless detection of analytes (such as bacteria) labeled by electrically, dielectrically, or magnetically active nanoparticles, for example in quality control monitoring for food supply chain management. The disclosed apparatus includes a detection vessel or vial, a resonant sensor tag, an inductively coupled reader to induce and detect resonance in the sensor tag, and an active nanoparticle for labeling. The disclosed wireless detection apparatus and methods use active nanoparticles for the development of wireless sensor systems which can be designed to be compatible with the existing RFID technology infrastructure. For example, commercial RFID readers (e.g., hand-held) used for tracking and tracing operation can be used with the disclosed apparatus to induce and measure a corresponding resonance frequency.

摘要： A heterojunction device is provided. The heterojunction device includes a silicon (Si) substrate; and a film of silicon carbide (SiC) deposited on a surface of the Si substrate. The SiC has a Si:C ratio that increases or decreases from a SiC surface in contact with the Si substrate to an opposing SiC surface that is not in contact with the Si substrate.

摘要： A method for forming a compound on a substrate is provided. The method includes depositing a composition onto a surface of a substrate; illuminating the composition and the substrate with pulsed energy; melting the substrate and decomposing the composition simultaneously; and forming a compound on the substrate. A first component of the compound is derived from the substrate and a second component of the compound is derived from the composition.

摘要： A multiband sensing system includes an active multiband sensing unit configured to transmit a radio frequency (RF) signal in multiple bands and communicate with a network. The active multiband sensing unit includes at least one transmitting antenna configured to transmit the RF signal. The multiband sensing system includes a passive multiband sensing unit including at least one receiving antenna configured to receive the RF signal, an acoustic actuator powered by the received RF signal including an actuating sensor element configured to actuate in response to receiving extracted modulated information of the RF signal, and an acoustic detector. The acoustic detector includes a detector transmitting antenna configured to backscatter a new frequency band signal to the active multiband sensing unit and a detector sensor element configured to sense data. The sensed data is modulated over the received RF signal to produce the new frequency band signal.

摘要： A harmonic tag system includes a harmonic tag and a first antenna configured to receive a fundamental signal and transmit an identifier of the harmonic tag at a fundamental frequency. The harmonic tag system includes an energy harvesting unit configured to convert the fundamental signal into power. The power activates a sensor. The harmonic tag system also includes a harmonic doubler configured to generate a harmonic signal at a harmonic frequency based on (i) the fundamental signal and (ii) a sequence. The harmonic tag system further includes a digital modulation unit configured to selectively trigger an activation of the harmonic doubler. The harmonic doubler is triggered sequentially in an off state and an on state, and the digital modulation unit produces the sequence. The harmonic tag system also includes a second antenna configured to transmit data of the sensor at the harmonic frequency.
