TOUCH SENSORS WITH TACTILE FEEDBACK

摘要

Touch sensors with one or more piezoelectric elements and devices containing such touch sensors are presented. The touch sensor contains keys that are independently actuated. Contact with a key provides tactile feedback through the piezoelectric element to the user. Each key provides an individual tactile feedback pattern that is dependent on the particular key contacted as well as the function of the key at the time of contact. Actuation of the key provides a different tactile feedback pattern. The piezoelectric element is bonded directly to a printed circuit board, on which electronic components are also mounted.
