Abstract

Due to the high rates of dehydration occurring among hospital patients and the impact that it inflicts upon recovery efforts despite the awareness among the populous and medical staff, a novel device to aid in the diagnosis of the biological state has been deemed to be necessary. While other methods to measure the hydration state of patients do exist, they rely on collecting urine samples and undergo testing cycles or depend on the user sweating into collection units. Our device differs from this standard approach by consolidating the size of the testing equipment to a wearable biometric monitor that can fit into the palm of your hand and works by measuring the conductivity of the skin to obtain a reliable reading of a person’s hydration. Whether being worn while running on the tracks or being worn in the hospital ward, the transdermal sensor is able to collect a reading from the multiple probes that easily make contact on the skin with limited irritation to the user and can transmit the data to a mobile device via Bluetooth for a straightforward result.

The design team has gone to great lengths to put forward this device featured here. The multilayered structure is composed of several biocompatible materials that are non-riratable while being built to last for extended periods of time for multiple uses. In addition, a UI program has been created for the patient to check their biometric while having it be calibrated to fit their personal state. Along with this is the design of the sensor probs to obtain reading from the skin with minimal data corruption from the sweat that may form.
