Two- and three-axis motion and cursor control force sensors provide a linear output in all three axes, resulting in smooth motion control. The sensors have been tested to 10 million cycles in all three axes. The sensing element consists of a ceramic substrate with a perpendicular post. As force is applied to the top of the post, the substrate microscopically deflects, producing strain couples in specific areas of the substrate. The magnitude of the strain in the X, Y, and/or Z axis defines the direction and rate of motion.

In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
