  • Two-Terminal Voltammetric Microsensors

  • US Patent:
    52231178, Jun 29, 1993
  • Filed:
    May 3, 1991
  • Appl. No.:
    7/695254
  • Inventors:
    Mark S. Wrighton - Winchester MA
    James J. Hickman - Falls Church VA
    Paul E. Laibinis - Plains PA
    David Ofer - Newton MA
    Chad A. Mirkin - Skokie IL

  • Assignee:
    Mass. Institute of Technology - Cambridge MA
    Pres. & Fellows of Harvard College - Cambridge MA
  • International Classification:
    G01N 2726
  • US Classification:
    204415
  • Abstract:
    Self-assembly of a chemically insensitive redox material, such as ferrocenyl thiol, and a chemically sensitive redox material, such as a quinone thiol, onto microelectrodes forms the basis for a two-terminal, voltammetric microsensor having reference and sensor functions on the same electrode. Detection is based on measuring the potential difference of current peaks for oxidation and reduction of the reference (ferrocene) and indicator (quinone) in aqueous electrolyte in a two-terminal, linear sweep voltammogram using a counterelectrode of relatively large surface area. Use of microelectrodes modified with monolayer coverages of reference and indicator molecules minimizes the size of the counterelectrode and the perturbation of the solution interrogated. Key advantages are that the sensor requires no separate reference electrode and the sensor functions as long as current peaks can be located for reference and indicator molecules.
  • Condition Tester For A Battery

  • US Patent:
    56274726, May 6, 1997
  • Filed:
    Jan 26, 1995
  • Appl. No.:
    8/378688
  • Inventors:
    David Ofer - Newton MA
    Gary M. Searle - North Smithfield RI
    Joseph Bernier - Cambridge MA
  • Assignee:
    Duracell Inc. - Bethel CT
  • International Classification:
    G01N 27416
    G01R 3136
  • US Classification:
    324435
  • Abstract:
    A tester for determining the condition of an electrochemical power source, e. g. a battery or main cell, is disclosed. The tester may comprise an electrolytic (coulometric) cell connected in series to a auxiliary cell. The auxiliary cell is a miniature electrochemical power cell. The electrolytic (coulometric) cell may have no electromotive force of its own and may comprise an anode and cathode of the same material, desirably silver, with an electrolyte contacting at least a portion of both the anode and cathode. The tester may be permanently connected in parallel to a main cell being tested and is thin enough to be integratable into a label for the main cell. As the main cell discharges, the electrolytic cell anode clears proportionally to the discharge of one of the electrodes of the main cell to provide a continuous visually discernible indication of the state of charge of the main cell.
