Wearable and Flexible Electrochemical Biosensors for Continues Healthcare Monitoring


350 Health & Human Development Building

Wearable and flexible electrochemical biosensors represent a transformative advancement in continuous healthcare monitoring, addressing the growing demand for non-invasive, real-time, and personalized health insights. These cutting-edge devices leverage innovations in materials science, nanotechnology, and microfabrication to enable precise tracking of critical biomarkers in sweat, such as glucose, lactate, pH, and electrolytes, which reflect key physiological states and metabolic health. This talk will explore the integration of laser-induced graphene (LIG) with nano- and biotechnology to create highly sensitive, long-term stable, and fully flexible sensing platforms. By overcoming the limitations of current technologies, such as limited durability, rigid form factors, and the need for high sensitivity, these biosensors advance the field significantly. Furthermore, the multiplex sensing platform incorporates pH and temperature sensors alongside a flexible microfluidic sweat sampling network, enabling accurate continuous, non-invasive on-body biomarker detection with real-time calibration to account for pH and temperature variations. This cost-effective and robust platform holds immense potential for early disease detection, personalized medicine, and treatment evaluation, paving the way for widespread adoption in non-invasive healthcare applications and enhancing global health outcomes.

Electromechanical coupling at the nanoscale: The ubiquitous case of flexoelectricity

350 Human Health and Development Building
3:35-4:25 pm

I will discuss a recent experimental observation focused on self-assembled graphene NWs formed on flat MoS2 substrates. The mismatch in elastic properties between these materials creates strain gradients, which we mapped using sub- micro Raman spectroscopy. Conductive atomic force microscopy (c-AFM) measurements revealed consistent, reproducible flexoelectric currents under appropriate bias potential across extensive networks of dense NWs This research establishes graphene NWs as an ideal system for investigating strong flexoelectric effects. The findings highlight significant potential applications in strain-engineered nanoscale electronic and electromechanical devices, opening new avenues for harnessing this phenomenon in future technologies. This work bridges theoretical predictions with experimental validation, advancing our understanding of how nanoscale structural deformations in 2D materials can be leveraged for novel electronic properties and functionalities.
