PIEZOELECTRIC ELEMENT FOR KEYBOARDS |
摘要 |
<p>A monolithic piezoelectric key structure having a piezoelectric layer adherently connected between two conductive areas. The piezoelectric layer is applied as a fluid on the base conductive area and transformed into a coherent solid adhering to the base conductive area. The other conductive area is adherently formed on the piezoelectric layer. The monolithic structure is polarized.</p> |
