Transparent Strain Sensors in an Electronic Device

摘要

An electronic device includes one or more transparent strain sensors configured to detect strain based on an amount of force applied to the electronic device, a component in the electronic device, and/or an input surface of the electronic device. The one or more transparent strain sensors may be included in or positioned below an input surface that is configured to receive touch inputs from a user. The area below the input surface can be visible to a user when the user is viewing the input surface. The one or more transparent strain sensors are formed with a nanostructure, including a nanomesh or nanowires.

1. An electronic device, comprising:
an input surface configured to receive touch inputs; a strain sensitive structure positioned below the input surface, the strain sensitive structure comprising:
a transparent insulating substrate; anda first transparent strain sensor formed with a nanostructure and positioned on a first surface of the transparent insulating substrate; and a processing device operably connected to the first transparent strain sensor and configured to determine an amount of force applied to the input surface based on signals received from the first transparent strain sensor.
