Identifying suppliers - search the Design News articles archives. Lots of times there are articles on devices - from sensors to microcontrollers and more, that show good comparisons with background information.
Q. What factors I need to consider to choose, for example, a pressure sensor for a medical application?, Can I choose any sensor from the market or it has to be special?. Thank you.
Sensing in medical applications can pose a few callenges. The first level is whether the sensing is external or internal. Obviously thermometers can address internal (but not invivo) measurements rather easily. Internal blood pressure measurements have specifcations that have been developed. Some sensor suppliers caution against the use of their products in medical applications.
Since you are checking pressure drop across a filter, what is the system pressure.
This would determin the common mode presure the sensor must tolerate.
Good point. I should have stated air filtering in a computer system. If this was a high pressure water flow application, the common mode pressure would certianly been a top level cosnideration and it would have added packaing complexity to the decision. For air filter monitoring, many pressure sensor suppliers address this type of application and the comon mode pressure is not normally an issue.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
