Abstract

A wearable analyte breath alert device and method for non-invasive monitoring of an analyte in a sample from a user. The device comprises an outer casing, a forward face having an in-line insignia, a front port and an activation button, a rear face having a detector threshold region, a side port and a LED indicator, a reversible core having a main processor module and a volatile organic compound (VOC) sensor adaptable to detect at least one volatile organic compound of the user. The VOC sensor further comprises a central sensor circuit having at least one nano gas sensor, a sensor signal conditioning unit and an A/D interface. The central sensor circuit is operably connected to a Bluetooth Low Energy (BLE) element having a microcontroller. An alarm component is coupled with the BLE element that alerts the user based on the analyte detected by the nano gas sensor.
