Soft Biomedical Devices for Modulating, Measuring and Exploiting Thermal Physiology


The intimate physical coupling of soft sensors and actuators with biological tissue represents a powerful avenue for providing physiological insights and altering biological function. This talk will describe mechanically-soft, compliant biomedical devices which modulate, measure, and exploit thermal functions in soft tissue for applications in health monitoring and therapeutics. This work spans the development of stimuli-responsive materials, 3D mesoscale assembly techniques, and integration and fabrication schemes for biomedical systems. These advances in materials engineering form the basis for soft, flexible bio-integrated device systems for 1) targeted, on-demand blocking of peripheral nerve activity via a soft microfluidic cooler comprising naturally bioresorbable materials, 2) non-invasive in situ biophysical/biochemical analysis of the epidermis and sweating response via skin-mounted devices comprising soft microfluidic valves, pumps, collection chambers, wireless digital thermography systems, and water barrier schemes, and 3) physiologically-responsive, shape-changing electronic systems which soften and mechanically deploy into preprogrammed states upon implantation.


Jonathan Reeder is a postdoctoral researcher in the Materials Science and Engineering Department at Northwestern University in the John Rogers Research Lab where his research focuses on soft, flexible electronic and microfluidic systems for digital medicine. His research interests include wearable devices, human-machine interfaces, implantable electronics, biosensors, and shape-programmable soft matter. From 2012-2016 he was an NSF Graduate Research Fellow in the Materials Science and Engineering department at the University of Texas at Dallas where he developed soft, shape programmable electronic systems for biomedical implants and electronic skins. During this time he also served as a founder and research director of Pascalor Inc, a startup that which worked to commercialize flexible temperature and pressure sensors developed during his PhD.
