The circuit protection connection for wearables and the IoT
by JAMES COLBY, Littelfuse Circuit protection technologies and board layout strategies help promote safety, reliability and connectivity. There’s one down-side to wearable technology that is unlikely to show up in headlines about the IoT: Human bodies generate static electricity as they move. That static electricity can potentially harm the sensitive electronics that power IoT applications. […]
