Abstract:
An apparatus includes an optically transparent sheet having an electrically conductive layer, an electrode element, and electro-vibration circuitry configured to provide a time-varying voltage signal across the electrically conductive layer and the electrode element so as to cause a user to experience electro-vibration in a first body part of the user when the first body part is moved across an exterior surface of the optically transparent sheet while a second body part of the user is in contact with the electrode element.
Abstract:
A sensing device is provided for measuring flexural deformations of a surface. Such a sensing device may be used as a user interface in portable electronic devices. The sensing device comprises at least one cell. The cell comprises a first electrode, a central electrode, a second electrode, a first piezoelectric sensing layer placed between the first electrode and the central electrode, a second piezoelectric sensing layer placed between the central electrode and the second electrode, and a circuit connected to the first, second and the central electrodes. The circuit is configured to measure a first electrical signal between the first electrode and the central electrode, and a second electrical signal between the second electrode and the central electrode. At least one of the first electrical signal and the second electrical signal is responsive to an external stress applied on the sensing device.
Abstract:
A method comprises capturing at a first device electrical energy of electromagnetic waves transmitted by a second device. The method further comprises using the captured electrical energy for causing a modification of a visual appearance of a display component. In addition to the wireless power, the visual appearance may depend on a data transmission.
