Printed Flexible Solar Cells Provide Embedded Renewable Power

In the effort to produce inexpensive, easily manufactured sources of sustainable, renewable power, solar cells continue to be a major focus — particularly flexible solar cells that can be applied directly to surfaces. Flexible solar cells are nothing new, but the methods by which they are made have progressed significantly in recent years.

Linear Motors and Actuators Meets Automation Needs

Linear motors and actuators are now cost-competitive with ball screws and belt drives and offer distinctly superior agility and bandwidth for advanced positioning applications. New micromotors and actuators are helping to automate tasks not previously feasible. Direct linear drives are increasingly replacing servo-controlled pneumatic cylinders, contributing reliability and controllability, free from the cost, noise, and upkeep of air compressors.

Thermographic Imaging Selecting an IR Camera with the Right Detector

The thermographic imaging characteristics of an IR camera are largely determined by its detector assembly. Infrared radiation (IR) is focused onto the camera’s detector assembly, which is a focal plane array (FPA) that converts IR into a visual image depicting temperature variations across the camera’s field of view (FOV). The FPA consists of thousands of pixels, which could be fabricated from any one of the IR sensitive materials commonly used in these cameras. Most detector materials respond to a selected portion of the IR spectrum (Figure 1). Therefore, a camera selected for any given application should have the appropriate FPA material based on the IR characteristics of objects within the FOV and the user’s study objectives.
