英文摘要
DESCRIPTION (Unedited Applicant's Abstract): The goal of this project is to
develop an advanced, miniaturized, all solid hybrid capacitor type
(Electrochemical-Electrolytic) for the next generation of implantable
defibrillators. The capacitor consists of a modified porous tantalum oxide
structure of a high-voltage electrolytic type anode, solid ionomer electrolyte
and electrochemical redox pseudocapacitance Ruthenium oxide type cathode.
By combining the advantages of the electrochemical capacitor and the
electrolytic capacitor, the proposed design will yield a high voltage, small
volume and low Equivalent Series Resistance (ESR) device with simplified
packaging process. Besides the potential for volume and/or mass reductions,
which will significantly contribute to the clinically important efforts of
reducing the Size of the present implantable defibrillator, other inherent
characteristics of hybrid capacitor could be critical drivers for selection of
this technology for implantable defibrillators. High reliability and safety
have also significant impact on this technology.
Phase I will identify methods of improving tantalum anode structure, solid
ionomer electrolyte, and catalyst particulate of the cathode to increase the
energy density and reduce the size the capacitor resulting in more efficient
charge extraction and a more rapid rate of capacitor discharge. Packaging
strategies will be developed and identified. A unit capacitor will be
fabricated and operated to demonstrate concept feasibility.
PROPOSED COMMERCIAL APPLICATION:
The commercial potential of this application is significant, there are critical need for
reduced size, high energy density capacitor for the implantable defibrillators, in addition
this technologies are needed to open up a wide range for making other implantable
support devices. i.e., for nerve and muscle stimulation, possible, thus helping to increase
worldwide the market share of the US companies in these device segment.
