ABSTRACT:

The interweaving of functional materials with multiscale, multimaterial 3D-printing processes could enable the additive manufacturing of a diverse set of complex, flexible, multifunctional biomedical devices. To this end, the focus of this research talk is to introduce the 3D-printed biomedical devices with unique geometries and extraordinary functionalities that can be utilized for biomedical applications, including bionic systems, wearable biosensors, and artificial organs. Firstly, a novel high-performance multimodal haptic system on prosthetics, consisting of conformal and modular sensing units for pressure, temperature, and texture detections, will be introduced. This system will be used as a sensing module for a bionic skin system for restoration of  multimodal haptics for amputees. Secondly, multiple 3D-printed wearable biosensors with unique microfluidics, micro-needles, and signal amplification for colorimetric or electrochemical sensing will be introduced. The biosensors can be used for in-situ disease management and health monitoring. Thirdly, a 3D-printed dynamic heart model with physical properties of tissue and integrated electronic sensors will be presented and its applications for edge-to-edge repair on defected mitral valve to reduce regurgitation will be discussed.
