Abstract: Flexible touch sensor panels can be implemented on a strap of a wearable device. A flexible touch sensor panel can provide an additional touch sensitive surface for a user to activate functions on the wearable device without covering a touch screen of the wearable device. In some examples, the flexible touch sensor panels can include electrode connectors configured to electrically couple touch electrodes of the flexible touch sensor panel. In some examples, the electrode connectors can have a serpentine routing pattern configured to allow the touch electrodes to move closer together or farther apart while maintaining electrical coupling between the touch electrodes. In some examples, the touch electrodes can have gaps configured to allow light to pass through the gaps. In some examples, an LED panel can be formed below or one or more waveguide layers can be formed above the flexible touch sensor panel.
