Patent number: 11422134Abstract: Disclosed herein are example embodiments of a transformative sensor apparatus that is capable of detecting and quantifying the presence of a substance of interest such as a specified bacteria within a sample via changes in impedance exhibited by a detection electrode array. In an example embodiment, sensitivity is improved by including a focusing electrode array in a rampdown channel to focus a concentration of the substance of interest into a detection region. The focusing electrodes include an opposing pair of electrodes in a rampdown orientation. The focusing electrode may also include tilted thin film finger electrodes extending from the rampdown electrodes. In another example embodiment, trapping electrodes are positioned to trap a concentration of the substance of interest onto the detection electrode array.Type: GrantFiled: April 29, 2019Date of Patent: August 23, 2022Assignee: The Curators of the University of MissouriInventors: Mahmoud Almasri, Shibajyoti Ghosh Dastider, Shuping Zhang, Majed El Dweik, Nuh Sadi Yuksek, Ibrahem Jasim, Jiayu Liu

Patent number: 11005352Abstract: An energy harvesting device for generating electrical power from low-frequency oscillations includes a high-frequency cantilever, a plurality of low-frequency cantilevers each configured to contact the high-frequency cantilever in response to environmental vibrations having a frequency within a near-resonance frequency range associated with said low-frequency cantilever, an a generator that produces electrical power in response to contact between at least one of the plurality of low-frequency cantilevers and the high-frequency cantilever. The energy harvesting device may also include an impact mass coupled to a free end of each of the plurality of low-frequency cantilevers. Some aspects may include a common base to which the high-frequency cantilever and the plurality of low-frequency cantilevers are coupled. Other aspects may include the generator comprising one or more of an induction coil and magnet, a variable distance capacitor, or a piezo-electric material.Type: GrantFiled: July 16, 2019Date of Patent: May 11, 2021Inventors: Nuh Sadi Yuksek, Mahmoud Almasri
