Next-generation wearable sensors that enable continuous real-time multimodal measurement of physical parameters (heart rate, heart rate variability etc.) together with biochemical markers (such as pH, concentration of electrolyte ions, metabolites, therapeutics) would be a transformative technology for personal fitness, wellbeing and diagnostics. 

In this interdisciplinary project we intend to implement multimodal biomarker determination using a single wearable optoelectronic platform integrated with optical (bio)chemical sensing capability in the form of chemically responsive skin patches or dermal tattoos. 

Simultaneous monitoring of biochemical analytes on the same sensing platform as physical signals will significantly enhance the utility and function of wearable devices. Signal analysis and pattern recognition methods employing artificial intelligence (AI) and machine learning (ML) algorithms might identify new and previously unknown relationships in multimodal physical and biochemical datasets, that ultimately leads to improved understanding of human physiology, health and wellbeing.
