  • Publication number: 20210371846
    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: 20200292482
    Abstract: Methods and systems for monitoring the activity of electrogenic networks are described. One representative system includes an array of electrode coupled to an analyzer having a stimulator and a receiver. The electrode is placed in contact with an electrogenic cell. The electrodes can be shaped as nanowires, tubes, cavities and/or cones. The analyzer may be configured to operate in a voltage stimulation mode, in which the cells are stimulated via voltages and monitored via current, or in a current stimulation mode, in which the cells are stimulated via currents and monitored via voltages. The analyzers may be arranged as single-stage amplifiers, and may include a feedback loop shared between the stimulation signal path and the sensing signal path. The feedback loop may be arranged to provide overlapping stimulation and sensing of the electrogenic network's cells.

  • Publication number: 20100003415
    Abstract: A high voltage ceramic and glass insulator with a function film is provided to resist pollution flashover and a preparation method is provided to produce the high voltage insulators. It is a common high voltage insulator covered with a layer of nano meter level inorganic film with the function of raising pollution flashover resisting, and the film is formed on the high voltage ceramic and glass insulator surface and made of a solution containing the titanium dioxide base, and the solution containing the titanium dioxide base includes a pure titanium dioxide solution or a binary compound oxide solution containing the titanium dioxide. The invention is suitably used for the power transmission and the transform line in the areas with the circumstance seriously polluted or in the remote mountainous areas.
