Picking up EEG signals is little delicate. Doctors use many electrodes and they do it. This news shows that it looks like a head band and can be fixed easily like a head phone and this has internal processing and also wireless connectivity to the doctor's computer. The S/N ratio of 25 db seems to be on the lower side. The battery stays for a couple of days. Good news!
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.
