Contracting and Elongating Materials for Providing Input and Output for an Electronic Device

A haptic structure comprising:

• a substrate;
• and
• a haptic actuator, mechanically coupled to the substrate and comprising,
• a piezoelectric material;
• and
• at least one electrode coupled to the piezoelectric material;
• wherein:
• an electrical input received by the at least one electrode causes the haptic actuator to bend the substrate;
• and
• the substrate includes a channel at least partially surrounding an area of the substrate to which the haptic actuator is mechanically coupled.

An electronic device comprising:

• a cover glass with a first side forming an exterior surface of the electronic device;
• a display having a first side coupled to a second side of the cover glass, the second side of the cover glass opposite to the first side of the cover glass;
• a first support structure proximate to a second side of the display, the second side of the display opposite to the first side of the display, and the first support structure separated from the second side of the display to form a space between the display and the first support structure;
• a second support structure coupled to the second side of the display and the first support structure;
• a backlight assembly positioned at least partially in the space;
• a haptic structure mechanically linked to the first support structure;
• a battery positioned in the electronic device proximate to the first support structure and opposite to the display;
• and
• a force sensing element positioned between the battery and the first support structure,
• wherein:
• the haptic structure is operable to cause a deflection of the cover glass in response to a signal applied to the haptic structure;
• and
• the force sensing element is operable to detect an amount of force applied to the cover glass.
