3D-Printed Biomedical Devices:  Wearable Biosensors, Artificial Organs, and Prosthetic Electronics

Abstract:

The interweaving of design and materials with multiscale, multimaterial 3D-printing processes could enable the creation of complex, flexible, and multifunctional biomedical devices with unique geometries and advanced functionalities. This research talk will highlight our recent advances in 3D-printed biomedical devices for applications in wearable biosensors, artificial organs, and prosthetic electronics. First, multiple 3D-printed wearable biosensors featuring unique microfluidic structures, microneedles, and signal-amplification strategies for colorimetric or electrochemical sensing will be introduced. These biosensors offer promising capabilities for in situ disease management and continuous health monitoring. Second, a 3D-printed dynamic heart model that replicates key physical properties of cardiac tissue and integrates electronic sensors will be presented. Its application in studying minimally invasive edge-to-edge repair of defective mitral valves to reduce regurgitation will be discussed. Machine-learning-assisted manufacturing of high-fidelity artificial organ models will also be introduced. Third, a high-performance multimodal sensing system for prosthetics will be presented. The system consists of conformal and modular sensing units capable of detecting pressure, temperature, texture, and material properties. This technology represents a key sensing component of a broader bionic skin system with the ultimate goal of restoring multimodal haptic perception and improving performance for amputees.
