  • Patent number: 11833346
    Abstract: The present invention generally relates to nanowires. In one aspect, the present invention is generally directed to systems and methods of individually addressing nanowires on a surface, e.g., that are substantially upstanding or vertically-oriented with respect to the surface. In some cases, one or more nanowires may be individually addressed using various integrated circuit (“IC”) technologies, such as CMOS. For example, the nanowires may form an array on top of an active CMOs integrated circuit.

  • Patent number: 11768196
    Abstract: Methods and systems for stimulating and monitoring electrogenic cells are described. Some systems for stimulating electrogenic cells are based on the injection of electric currents into the cells via electrodes connected to the cells. Such stimulators may comprise an impedance element having an input terminal and an output terminal coupled to an electrode, and a voltage follower coupled between the input terminal and the output terminal of the impedance element, the voltage follower being configured to maintain a substantially constant voltage between the input terminal and the output terminal of the impedance element. The impedance element may comprise one or more switched capacitors at least in some embodiments. In some embodiments, the voltage follower may be implemented using a source follower.

  • Publication number: 20230184739
    Abstract: Disclosed herein are semiconductor devices to provide a CMOS-compatible, wafer-scale, multi-well platform that can be used for biomedical or other applications, and methods to operate the same. In some embodiments, circuitry is provided underneath a multiple-well array to electrically interface with electrodes in the wells. To interface with electrodes in a large array, circuitry may be fabricated on a single silicon (Si) wafer having a dimension that is at least the same or larger than that of the multiple-well array. According to one aspect of the present disclosure, standard CMOS fabrication process such as those known to be used in a standard semiconductor foundry may be used without expensive customization for complex fabrication procedures. This may help the production cost to be lowered in some cases.
