Designing proper circuit protection for wearables

As consumers become increasingly dependent on wearables, circuit designers are tasked with incorporating advanced circuit protection technologies that safeguard the device as well as the user. Without proper protection, the device’s sensor circuits, battery-charging interfaces, buttons or data I/Os could be irreparably damaged by ESD that is often caused by close interaction with the user.
