Unfortunately, Cochlear has refused to properly space their electrodes, trying to jam 24 contacts (22 + 2 grounds) on the inch-long array into the pea-sized hearing organ. Because of this, channel crossover is a problem, where a given electrode stimulates the wrong part of the spiral ganglion, causing all sorts of problems.

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.
