Bioelectronics for Living Machines

John Rogers

Northwestern University

Advanced electronic/optoelectronic technologies that allow stable, intimate integration with living organisms will accelerate progress in biomedical research. These systems, sometimes referred to as bioelectronics, will also serve as the foundations for new approaches in monitoring and treating diseases. More recent opportunities are in the development of hybrid constructs that blend electronics with soft tissues in engineered platforms that are capable of executing desired functions, i.e. machines. This presentation describes the core concepts in materials science and engineering that underpin these technologies, with an emphasis on 3D mesoscale electronic frameworks and their interfaces with skeletal muscle rings, cardiac tissues, spinal spheroids and cortical assembloids. Demonstrations include wirelessly controlled biobots that use optogenetically stimulated contractions of muscle tissues for programmed locomotion.

Biological and Bioinspired Magnetic Reception and Multimodal Sensing

Brian K. Taylor

Case Western Reserve University

Global Navigation Satellite Systems (GNSS) such as the United States’ Global Positioning System (GPS) provide navigation information for applications that underpin society (e.g., international trade and travel, global security). However, satellite-based navigation technologies can become compromised or unavailable for a variety of natural and manmade reasons. These technologies are also expensive to deploy and maintain, and cannot be used in underwater applications. In contrast, a variety of animals migrate across long distances using only their natural born senses. In particular, different species of insect, fish, bird, turtle, and marine mammal use the earth’s magnetic field (i.e., magnetoreception) as an omnipresent sensory cue to aid in navigation and migration across continents and oceans. Despite decades of research, the sensory and processing mechanisms that underpin magnetoreception and its resulting navigation remain enigmatic. This talk will discuss the ongoing efforts of the Wisdom and Knowledge from Animal Navigation, Direction and Action (WAKANDA) Laboratory at Case Western Reserve University to probe animal and animal-inspired magnetoreception and multimodal sensing. To understand how animals sense and use the magnetic field to navigate, and to identify principles that can aid in developing the next generation of engineered navigation systems, WAKANDA uses an interdisciplinary approach that includes robotics, engineering, computational neuroscience, neuroethology, and modeling and simulation. Current laboratory activities include 1) analyzing hypothesized magnetoreception navigation strategies, 2) using computational neuroscience to understand sensory processing and integration, and 3) exploring a range of potential manmade applications for animal magnetoreception and multimodal sensing.

Leveraging Mammalian Motor Control Systems for Soft Robotics

Ritu Raman

Massachusetts Institute of Technology

Human beings and other mammals navigate unpredictable and dynamic environments by combining compliant mechanical actuators (skeletal muscle) with neural control and sensory feedback. Abiotic actuators, by contrast, have yet to match their biological counterparts in their ability to autonomously sense and adapt their form and function to changing environments. We have shown that engineered skeletal muscle actuators, controlled by neuronal networks, can generate force and power functional behaviors such as walking and pumping in a range of untethered robots. These muscle-powered robots are dynamically responsive to mechanical stimuli and are capable of complex functional behaviors like exercise-mediated strengthening and healing in response to damage. Our lab uses engineered bioactuators as a platform to understand neuromuscular architecture and function in physiological and pathological states, restore mobility after disease and damage, and power soft robots. This talk will cover the advantages, challenges, and future directions of understanding and manipulating the mechanics of biological motor control.
