Episode 56: Biotechnology 3- How Medical Devices Interface and Integrate with our Body Systems


Episode Summary:

This episode reviews the progress in developing biomaterials that allow for external and internal non-invasive interfaces with our various organs. A leading researcher examines the requirements for such materials and shares some recent device developments.


Dr. Chris J Bettinger, Ph.D.:

Christopher Bettinger is a Professor at Carnegie Mellon University in the Departments of Materials Science and Engineering and Biomedical Engineering. He directs the Laboratory for Biomaterials-based Microsystems and Electronics at CMU, which designs materials and interfaces that integrate medical devices with the human body. Dr. Bettinger has published over 90 articles and issued over ten patents. He has received numerous honors, including the MIT Tech Review TR35 Top Young Innovator under 35 and the DARPA Young Investigator Award.

During This Episode, We Discuss:

  • The challenges of interfacing device technology with humans. Think of fitting a device to curved tissue that’s flexible, miniature, and allows for continuous monitoring.
  • Materials Science: Bio-Inspired Materials
  • Embedded Electronics
  • Noninvasive monitoring of the human Gastrointestinal tract

Quotes (Tweetables):

“In your gut, there are also 100 million neurons, organized into complex networks, localized computational functions, sensory feedback, mechanosensation, the gut is the third brain.”

Dr. Bettinger

“We could be interfacing with the neurons in the gut, and we are developing technologies that enable that interface.”

Dr. Bettinger

“Gut health is interesting and is underappreciated…. What is a leaky Gut? What about devices that could measure physical properties of the gut, where you could get a quantitative lens on what is now a semi-qualitative descriptor.”

Dr. Bettinger

Carnegie Mellon University, Faculty, Dr. Chrisopher J Bettinger.

Episode 62: Understanding Obesity, New Concepts and Therapies

Obesity is a chronic disease associated with related conditions such as cardiovascular disease(heart attack and stroke), type 2 diabetes, and certain cancers. The current understanding of obesity demonstrates biological and environmental factors like economics and infrastructure, as psychosocial and developmental issues as essential contributors, and a newer understanding of their role in influencing the hypothalamus.

New treatment strategies and medications demonstrate opportunities for success in the management of obesity.New treatment strategies and medications demonstrate opportunities for success in management of obesity.

In this two part episode we explore where the modern male finds himself. We review data demonstrating a trend of increasing gaps in educational achievement, increasing rates of male suicide, and addictions, the preponderance of males in the homeless population and the decline in males participating in key careers.
