The Apple MacBook team has developed a pressure-sensitive input structure for electronic devices. It has already been approved by the US Patent and Trademark Office.
The structure consists of a metallic contact layer on the outside, a sensor layer and ends with an insertion layer. In addition, the structure can also be provided with an alignment layer located between the sensor layer and the insertion layer, as well as a rigid base layer. A set of supports can also exist between the metal contact layer and the rigid base layer.
Devices with such a structure will have a metal housing connected to a contact layer that attaches to the lower base layer. This device includes a group of holes forming a contact layer above the entry layer. Both of the above sections are partially flexible.
The main purpose of such a complex input device is related to durability. Namely, because conventional input devices such as keyboards are often prone to damage, these new electronic devices and input sensors have been designed to be more resistant to incidents such as water spills or a bump from a fall.
Finally, by manufacturing these devices and customizable input structures inside a metal case, the designers strive to protect all electronic components inside a kind of shield. In this way, these devices can avoid the problem faced by typical input devices where, if one section is damaged, the entire device may become unusable.
For ease of use, the shape and size of these input devices can be changed and reconfigured to adapt to a variety of hardware, software, and other types of electronic devices.
