Abstract:
A pressure sensor assembly including:first and second substrate sections;a first and a second pressure sensor electrode formed at a distal end of said first and second substrate sections respectively;a layer of a pressure sensitive material over at least one of said electrodes;a first, a second, and a third terminal at a proximal end of said first substrate section and a fourth terminal at a proximal end of said second substrate section;first and second leads on said first substrate section, said first lead electrically connecting said first and second terminals, and said second lead electrically connecting said first electrode and said third terminal;a third lead on said second substrate section which electrically connects said second electrode and said fourth terminal; anda window formed at the proximal end of said second substrate section;said first and second substrate sections being secured together adjacent each other, said electrodes, terminals, leads and window being arranged on their respective substrate sections such that when the substrate sections are secured together, said first and second electrodes are adjacent, with said pressure sensitive material therebetween to form a pressure sensor, said second and third leads are on opposite sides of the assembly so as not to contact each other, said first and fourth terminals are adjacent each other, and said window overlies said second and third terminals to permit electrical contact to be made with these terminals through said second substrate.
