What is the incremental cost of this new IMU technology on top of a supporting GPS? It would be interesting to see where else it could be used. As a 23 mm cube = 1 square inch, it sounds like it is still too large (or was there an error in the dimensions in the article) to incorporate into a mobile phone. How much might the pricing come down with high volume production? If affordable (and small enough), it would be a natural replacement for any GPS system to improve accuracy when out of range of the satellites.
IMUs have been available for years, as part of the inertial guidance systems of everything from ships to spacecraft to missiles. However, by incorporating cheap MEMS sensors, instead of expensive ring-laser gyros, TRX and other OEMs are bringing down the price of location tracking for a variety of applications, from finding people to protecting important assets.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
