报告摘要

可植入人体内的电子器件不仅可以提供重要生理信号的检测,同时还可以为包括心脏功能失常等在内的严重疾病提供及时治疗。然而在第一次植入电子器件后,我们需要再进行第二次手术来取出相关器件。与此同时,传统的电子器件需要在脆弱的硅片上进行平面加工制造,而这是和人体的复杂曲面不兼容的。为了解决这两个重要问题,我们设计并制造了具有柔性的医学器件。这一柔性医学器件不仅可以穿戴在人体复杂的皮肤表面,而且在完成功能后完全溶解在人体内。结合我们研究小组之前的柔性电子技术,本次讲座主要介绍一套可以在人体内溶解的功能材料体系,使得这一新的医学器件可以被穿戴在人体内部的重要器官上,在它们设定的医学应用时间内稳定运行,而在此之后可以完全溶解在人体内。

 

 

ABSTRACT:

Recent advances in electronics enable powerful biomedical devices that have greatly reduced therapeutic risks by monitoring vital signals and providing means of treatment.  Implantable devices can help us better understand the behavior and effects of various diseases.  However, an additional procedure is required to remove the device after an initial implantation.  Conventional electronics today form on the planar surfaces of brittle wafer substrates and are not compatible with the complex topology of body tissues.  Therefore, stretchable and absorbable electronics are the two missing links in the design process of implantable monitors and in-vivo therapeutics.  This talk presents the challenges, mechanics, and design strategies, behind a potential medical device that (a) integrates with human physiology, and (b) dissolves completely after its effective operation. Implanted devices will provide a much better understanding of organ functions and offer more time efficient treatments for serious diseases such as heart failure.

 

Biography:

Dr. Huanyu Cheng was appointed an Assistant Professor of Engineering Science and Mechanics (ESM) and Materials Research Institute (MRI) at The Pennsylvania State University in Aug 2015, and was awarded the Dorothy Quiggle Career Development Professor in Sep 2015.  He earned a Ph.D. and a Master’s degree from Northwestern University in 2015 and 2011 respectively, and a Bachelor’s degree from Tsinghua University (China) in 2010.  Prior to joining Penn State, Dr. Cheng also worked as a Visiting Research Fellow with Prof. John A. Rogers at the University of Illinois at Urbana-Champaign on stretchable and transient electronics.  Throughout Dr. Cheng’s research career, he has worked on mechanics design and manufacturing of biologically inspired electronics with applications in robotics, biomedicine, and energy.  Dr. Cheng has co-authored over 50 peer-reviewed publications, and his work has been recognized through the reception of awards including Forbes 30 Under 30 2017 in Science, election to the Global Young Academy, a Haythornthwaite Research Initiation Grant from ASME (2016-2018), Finalist for Forbes 30 Under 30 list in Manufacturing/Industry in 2016, Howard Hughes Medical Institute (HHMI) International Student Research Fellowship, Best Paper Award in ASME Applied Mechanics Division Student Paper Competition, International Institute for Nanotechnology Outstanding Researcher Award, Chinese Government Award for Outstanding Self-financed Students Abroad, and many others.  He also serves as associate editor for Computers in Biology and Medicine, editorial board member for Informatics in Medicine Unlocked, and reviewer for 40 international journals.
