Abstract
Abstract Improved artificial palate for use in dynamic palatographical speech researches and improvements in the method of fabricating such artificial palate are provided. The artificial palate comprises a shell body mold-formed with an electrically insulative plastic material in conformity with individual user's palate. A flexible insulative circuit board includes a plurality of sensing electrodes provided in the board over the area thereof and lead wires printed on both surfaces of the board for connecting the respective electrodes to terminals arranged on both surfaces of the board adjacent an edge thereof. The circuit board is embedded in the shell body exposing the sensing electrodes on the inner surface of the body to be in contact with user's tongue during the use. Insulation coated wires connect the electrode terminals to the exterior and form means for mounting the artificial palate in user's mouth when embedded in the plastic material contiguous to the shell body. In the fabricating method, the circuit board is preliminarily prepared in different sizes, a proper size of the circuit board is selected to be joined to the mold-formed shell body, and the plastic material is applied over the board to embed it in the body but exposing the sensing electrodes on the tongue contacting surface.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
An artificial palate for use in dynamic palatographical speech research and which is of the type comprising a structure to be intimately fitted to a particular user's palate, said structure including a plurality of sensing electrodes supported by said structure so as to be contacted by a user's tongue during use, lead wires each connected at one end to a respective electrode, the other ends of said wires extending from at least an end portion of the structure, and means on the structure for mounting the structure within the user's mouth, the improvement wherein said structure comprises: a shell body formed of electrically insulative material in the shape of a particular user's palate, and a base board formed separately of said shell body of flexible electrically insulative material, with said lead wires formed on said base board in the form of a printed circuit applied with said base board being substantially flat, said base board being secured to a lower surface of said shell body such that said lead wires are sandwiched therebetween, and said base board being held in the shape of the user's palate solely by the connection between said base board and said shell.
