Abstract

Συσκευή χειρός (χειρολαβή) που φέρει ένα και μοναδικό σύνολο πιεζοηλεκτρικών στοιχείων πολωμένων για την παραγωγή διαμήκους κίνησης όταν διεγερθούν στη σχετική συχνότητα συντονισμού. Οι πιεζοηλεκτρικοί κρύσταλλοι συνδέονται σε κέρας υπερήχων στο οποίο έχει προσαρτηθεί ακίδα κοπής. Το κέρας και/ή η ακίδα κοπής περιέχει πλήθος διαγώνιων σχισμών ή αυλακιών. Οι σχισμές ή τα αυλάκια παράγουν βελτιστοποιημένη στρεπτική κίνηση στην ακίδα κοπής όταν οι πιεζοηλεκτρικοί κρύσταλλοι διεγερθούν σε δεύτερη συχνότητα συντονισμού. Κατά προτίμηση, οι δύο συχνότητες ενεργοποίησης δεν συμπίπτουν, αλλά παρέχονται με μη επικαλυπτόμενους παλμούς.
