Valencell has been granted an NSF Phase 2 STTR Award for developing a mobile, wearable, noninvasive blood analyte sensor that can be worn throughout everyday life activities. In contrast with traditional dual-wavelength pulse oximetry, which measures oxygen saturation in the blood, Valencell’s multiwavelength sensor will enable the real-time analysis of several additional metabolites critical to health and fitness monitoring. Furthermore, because multiple, individually controlled wavelengths can be generated from the same LED, a truly unobtrusive device can be worn without disturbing the user’s lifestyle. In this STTR Program, North Carolina State University (NCSU) will generate multiwavelength emitters, and Valencell will generate and validate mobile, wearable sensor modules integrating these multiwavelength emitters.
