Even though Dell Computers and others offer fingerprint reading security options on their computers, fingerprint reading technologies still seem to be a highly fragmented market in search of a strong customer base. "A Single-Chip Fingerprint Sensor and Identifier" was described and illustrated by Shigematsu et al in the December 1999 issue of the "IEEE Journal of Solid State Circuits". Why hasn't this market matured and consolidated into a mainstream product more than a decade later?
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.
