Abstract: An electronic device that is operable to provide electrical haptic output includes a touch surface and multiple haptic cells disposed on the touch surface. The multiple haptic cells include capacitors that are operable to store charges independently of each other and independently provide haptic output when touched by a body by discharging the stored charge to create a current. In this way, a wide variety of dynamically configurable haptic outputs can be provided without moving parts and without consuming the space and/or power used for haptic actuators that vibrate and/or otherwise move a mass.

Abstract: A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective at least one flexure mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. Each flexure may include two diverging arms joined together at proximal ends and having spaced distal ends operatively coupled between adjacent portions or the field member and the housing. The two diverging arms may each include a proximal segment having a reduced material medial portion relative to adjacent end portions, and a distal segment, being canted with respect to the proximal segment, and having a reduced material medial portion relative to adjacent end portions.
