Abstract

The increasing global demand for personalized healthcare technologies necessitates a new generation of wearable sensors that are high-performance, low-cost, and compatible with various platforms, including human organs. Low-temperature-processed hybrid and nanostructured materials enable such devices by allowing direct patterning onto 2D and 3D substrates through cost-effective printing processes. Their electronic and mechanical properties can be easily tuned through composition or morphology adjustments. In this presentation, I will describe how this material class facilitates novel wearable medical devices with unprecedented performance. Specifically, I'll focus on creating optical devices for noninvasive physiological measurements, including a high-gain high-speed photovoltage transistor for continuous vital sign tracking and a single-point spectrometer for multi-spectral photoplethysmography. Additionally, I will discuss our recent exploration of using quasi-two-dimensional Dion-Jacobson phase perovskites to achieve photonic structure-integrated light-emitting devices.
