Abstract

Access to medical monitoring in the field is primarily limited to physical or electrical measurements such as temperature, heart rate or respiration that readout a soldier’s immediate health. The ability to monitor biomarkers in combination with these measurement can uncover pathways leading to a health event and catch problems before the onset of symptoms. Our goal is to develop a fieldable, wearable PIC device for continuously monitoring small molecules and proteins. Continuous monitoring of biomarkers and physiological analytes is necessary for detecting abnormal fluctuations from baseline and provides real-time responses of human performance or injury. Wearable sensors for continuous monitoring require a combination of traits not seen in sample-based sensor systems including compact size, reversibility and sample replenishment. To accomplish this, we combine our expertise in sensors and photonic integrated circuits to generate a refractive index sensor platform. This approach takes advantage of sensing components and PIC devices to increase their sensitivity and selectivity for biomarkers while maintaining a small footprint required for practicality in the field. Here we report progress in striving to achieve a wearable sensor for continuously monitoring analytes in blood and sweat.
