Abstract:
An apparatus comprising a flexible substrate 201 and an overhanging electronic component island 202a wherein the rigid electronic component island comprises a substrate-face with a connection portion 221a and an overhang portion 222a, the connection portion being mechanically coupled to a surface of the flexible substrate via one or more central connection-support pad 203a and the overhang portion configured to overhang and be substantially free of the underlying flexible substrate such that the underlying flexible substrate can be strained independently from the overhang portion under operational strains of the flexible substrate. The central connection pad also removes stress within the components on the island. This connection mechanism allows adjacent component islands to overlap one another.
Abstract:
A template material layer having a periodic profile is formed on a flexible printed circuit board substrate whilst the substrate is maintained in a stress free state. Conformal thin film circuit board layers are subsequently deposited over the template material. The template material may a sacrificial material removable by etching or sublimation to form cavities between the thin film circuit board layers and the flexible substrate. Alternatively the template material may be retained. Electronic devices mounted on the thin film layers are subjected to reduced stress when the flexible circuit is stretched or bent when in use. The flexible printed circuit can be used where repeated stretching or bending is required in, for example, textile and folding display screen applications
Abstract:
An apparatus includes a separator/electrolyte assembly; a first energy storage portion disposed on a first surface of the separator/electrolyte assembly; a second energy storage portion disposed on a second surface of the separator/electrolyte assembly; a first metallized piezoelectric film disposed on the first energy storage portion; and a second metallized piezoelectric film disposed on the second energy storage portion. When a force is applied to the first metallized piezoelectric film, a piezoelectric effect converts mechanical strain into electric potential and each energy storage portion stores the energy converted in the first energy storage portion and the second energy storage portion for subsequent discharge from the first energy portion and the second energy storage portion to an electronic device.
Abstract:
Apparatus including a first surface electrode and an arrangement of second insulated surface electrodes; a display configured to display an image; and a controller configured to apply a potential difference between the first surface electrode and the arrangement of second insulated surface electrodes and configured to control at least a variation in the applied potential difference in dependence upon the displayed image.
Abstract:
A mixture including a room temperature ionic liquid; and a reversible source/sink of lithium ions. The mixture may be used as a lithium-ion battery electrode slurry enabling flexible lithium-ion batteries.
Abstract:
An apparatus including: a touch sensitive input responsive to manual actuation; a display output associated with the touch sensitive input; and a controller configured to provide and maintain, in response to a manual actuation at a user selected location of the touch sensitive input, an output at the user selected location to facilitate additional manual actuation via the touch sensitive input in the region of the user selected location.
Abstract:
An apparatus comprises a transformable body configured to be elastically stretchable between at least a first configuration and a second configuration, a user input device, a user input device configured to receive user input signal, a communication interface configured to provide a wireless link for the apparatus and a flexible interconnection between at least two components within the transformable body. The apparatus may perform determining of user information based on the user input signal, transmitting at least part of the user information over the wireless link to a remote processing unit, receiving feedback information from the remote processing unit and presenting the feedback information to the user.
