The methods and apparatuses (including systems and device) described herein may be used to accurately and comfortably monitor and track body temperature using a wearable device that can be positioned inside a patients ear for measuring the patients temperature, sleeping quality, or other vital signs. These systems and methods may also include a base station and a remote analytics unit (e.g., software, hardware or firmware, including application software that may run on a hand-held or wearable electronics device). The inter-aural device (earplug device) may record and pre-process information that may then be adaptively passed on the remote analytics unit for further processing. The earplug device may engage the remote analytics unit with to download and process the temperature measurement data from the device, to electrically charge the device and also to communicate wirelessly with a smart phone or different types of mobile devices.
