With a unique blend of expertise in materials science, electrical engineering, and biology, Khodagholy has pioneered innovative solutions that have the potential to revolutionize healthcare and biotechnology.
Advancing Flexible Electronics for Medical Applications
Professor Khodagholy’s research group at Columbia University has made significant strides in developing flexible electronics, pushing the boundaries of what was previously possible. Their work focuses on creating devices that are not only flexible and stretchable but also biocompatible, opening up a world of opportunities for medical applications.
Bio-Integrated Sensors: Monitoring Vital Signs with Comfort
One of the group’s notable achievements is the development of advanced sensors that can be seamlessly integrated with the human body. These sensors, made from organic materials, are designed to monitor vital signs such as heart rate, blood pressure, and body temperature. Unlike traditional rigid sensors, these flexible devices conform to the body’s natural movements, ensuring comfort and accurate readings.
For instance, their epidermal electronics can be worn like a temporary tattoo, providing continuous health monitoring without causing any discomfort or irritation. This technology has the potential to revolutionize patient care, especially in long-term monitoring scenarios, where traditional methods might be invasive or impractical.
Neuroprosthetics: Restoring Function and Mobility
Khodagholy’s team has also made significant contributions to the field of neuroprosthetics. By combining their expertise in flexible electronics with an understanding of neural interfaces, they have developed devices that can interact directly with the nervous system.
One such device is a stretchable neural probe designed for brain-computer interfaces. This probe, made from organic semiconductors, can adapt to the complex geometry of the brain, providing a stable and reliable connection. It offers a less invasive alternative to conventional neural probes, which are often rigid and can cause tissue damage over time.
