FRAMELESS ACOUSTIC SENSING DEVICE Russian patent published in 2015 - IPC G06F3/43 

FIELD: physics.

SUBSTANCE: acoustic sensing device contains the substrate capable to propagate surface acoustic waves, containing front, back surfaces and the curved connecting surface formed between the front and back surfaces; and at least one acoustic wave converter and at least one reflecting structure, and the acoustic wave converter and the reflecting structure are located behind the named back surface, meanwhile the acoustic wave converter is capable to transfer surface acoustic waves to the reflecting structure or to accept surface acoustic waves from the reflecting structure, and the reflecting structure is capable to scatter the surface acoustic waves on the named back surface for distribution of the named scattered surface acoustic waves between the named back surface and the named front surface through the named curved connecting surface.

EFFECT: making of the acoustic sensing device as frameless, possessing additional tactile functionality besides that is available in active sensing area.
