Personal Hydration Monitor System

Dehydration is one of the most subtle and dangerous threats facing soldiers in the field. In Phase I of the Personal Hydration Monitor (PHM) project, IEM demonstrated the feasibility of a micro-scale Hydration Monitoring Tag (HMT) for attachment to a tooth to monitor hydration through a unique MEMS osmolality sensor, wirelessly transferring this data to a Data Collection and Relay Unit (DCRU) which would analyze the data, alert the soldier to dangerous conditions, and relay the data to a Central Monitoring Station (CMS) which would track the condition of multiple soldiers. In Phase II International Electronic Machines Corporation (IEM) will develop working prototypes of the PHM suitable for Army use and development to a deployable system, focusing on the unique microelectronics for micro-scale multisensor-capable (obvious candidate sensors include temperature, “man down”, and biochemical monitors) wireless sensor tags for the HMT, with an accurate and reliable MEMS sensor, anti-fouling designs to permit in-mouth operation for extended periods (many months or even years), innovative MEMS-based energy storage technology to support this operation, and reliable and user-friendly wireless data collection and user-interface technology.. IEM will be assisted in this task by Dr. James Castracane of Albany Nanotechnology and Benjamin Park of Carbon Micro-Battery.
