QTC Clear is a force sensing material can be used to create Force
Sensitive touch screens that can replace current Resistive touch screen
technologies or enhance Capacitive ones to create solutions with more features
such as 3D input. The QTC Clear layer is 6-8 microns thick with a transparency
that is similar to the existing touch screen technologies. This is sandwiched
between two layers of Indium Tin Oxide, which is sandwiched between two hard
sheets, typically glass. It is sensitive that it can detect deflections of
a few microns so that the top surface can be rigid and robust, e.g. glass,
unlike current Resistive designs that have to be soft enough to deform easily
making them susceptible to damage.
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
