Bharath R. Takulapalli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9170228
    Abstract: A solid-state field-effect transistor sensor for detecting chemical and biological species and for detecting changes in radiation is disclosed. The device includes a porous or structured channel section to improve device sensitivity. The device is operated in a fully depleted mode such that a sensed biological, chemical or radiation change causes an exponential change in channel conductance.
    Type: Grant
    Filed: June 6, 2008
    Date of Patent: October 27, 2015
    Inventor: Bharath R. Takulapalli
