Novel Packaging Techniques for Electronics with Conformal Tissue Contact
Keywords: Conformal Electronics, Compliant Packaging, Soft Medical Devices
Developing advanced electronics for minimally invasive procedures and health monitoring is of central importance to advancing medical tools of the future. A key challenge is establishing durable, biocompatible interfaces between the classes of sensory devices and the soft, curvilinear surfaces of biological tissues. In this talk, we describe solutions whereby we integrate mechanically stretchable nanomembrane sensors on elastic sheets and 3-dimensional balloon surfaces to measure temperature, flow, contact, and electrophysiology data in clinical settings. The materials and mechanics concepts introduced represent fundamental improvements in the utility of otherwise conventional balloon and sheet-based catheter systems. Key advantages of these approaches include the capability to withstand mechanical deformation exceeding 200% without fracture or discontinuity in electronic performance. We describe key process approaches used to create these advanced medical tools and highlight practical applications currently under investigation.
