Materials selection criteria

This is a good introduction to materials selection in plastics.  Another important factor to consider is chemical compatibility.

Most of the factors mentioned here apply in a general sense to materials selection for metals, as well as plastics.

Overall, a very nice article.

I agree.  This is a very nice article.  It's good to revisit.

Dave-that's a good point about chemical compatibility.

Agency Requirements

Good article.  In many electromechanical assemblies, Agency requirements can matter also.  A polymer may be the perfect match for the strength, finish, etc. needed for the product.  However, that particular grade of polymer may not have the flame retardant properties needed to pass 94V-0 at the specified thickness in order to achieve agency certification for the entire product.  It is important to also consider agency requirements up front during product development to make sure the entire product can be certified.

The marriage of mechatronics know-how and advanced software tools is refining dynamic machine performance using measurements and innovative motion algorithms.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
The machine is claimed to be the largest and most powerful electric pipe-bender on the market, exerting nearly 500,000 lb-ft of torque.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
