ESD gets built up between human and earth. This device will either have its own local "ground" (isolated from the human body) or use the human body as its ground. Even if the potential between the human and earth is lots of kV, there wont be any problem, as no damaging current will flow between the electronics and the human. But it will need sufficient isolation between the electronics and earth (and maybe human) not to spark when bracelet gets between the human and a metallic earth surface.
This bracelet be programmed to do interesting artistic stuff when attached to a dancer :)
Wow!! New trends being set in fashion...and wearable electronics takes part there!! While pondering over wearable electronics circuit, a question occurred to me: how do we have a "real ground" for the circuit? How do we protect the circuit from the Electrostatic Voltage that gets generated in the body? Never thought about it.
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.
