The futuristic new tech that could bridge broken nerves and mend minds

The Future of Living Electronics: Transforming Medicine and Healing

Ian Burkhart was vacationing with friends in 2010 when a fateful dive into shallow water left him paralyzed from the shoulders down at just 19 years old. “At that point, I was reliant on assistance for everything,” he recalls. However, a breakthrough came a few years later when Burkhart received an experimental brain implant that rerouted nerve impulses from his brain around his damaged spinal cord, allowing him to regain limited use of his hands and arms, even enabling him to play the video game Guitar Hero. Despite initial success, the implant ultimately failed, highlighting a critical issue: the lifespan of medical implants.

The Challenge of Longevity in Implants

From pacemakers to deep brain stimulators, all types of medical implants suffer from a common issue: longevity. While pacemakers can last up to 15 years, devices such as deep brain stimulators may only function efficiently for three to five years. Burkhart’s experimental device lasted an impressive seven years before it needed removal, encouraging researchers to rethink implant design.

A New Dawn: Softer, Living Electronics

The emergence of soft, flexible electronics presents a promising solution to the challenges conventional implants face. Researchers around the globe are developing materials that not only mimic the human body’s soft tissues but can also grow alongside them. Some innovative designs incorporate living cells with electronics, forming a new class of “living electronics” that might enhance the compatibility and longevity of implants.

For centuries, humanity has understood the connection between electricity and biological systems. The Italian scientist Luigi Galvani first demonstrated this relationship in the 18th century by making frog legs twitch electrically. Today, we know that the human body operates through subtle electrical signals that underpin everything from heartbeat regulation to the healing process.

The Underlying Issues of Implant Failure

Modern medical implants integrate with the body’s electrical system to combat various ailments. For instance, pacemakers control heart rhythm, while deep brain stimulators mitigate neurological disorders like Parkinson’s disease. However, how well the body accepts these implants is highly variable. Over time, rigid implants can cause trauma to surrounding tissues, leading to inflammation and ultimately the formation of scar tissue, which can compromise implant functionality.

Exploring Softer Implant Designs

To enhance the compatibility of implants with human tissues, making them softer is a vital consideration. Major projects from companies like Elon Musk’s Neuralink and Precision Neuroscience are focused on developing implants that integrate smoothly with the brain tissue.

Research from Jia Liu’s lab at Harvard has produced incredibly soft electrode threads that are nearly invisible in water, yet durable enough for implantation. These new threads can accommodate many more electrodes, which can boost data acquisition and transmission without triggering a significant immune response. Consequently, these advanced implants may enjoy prolonged effectiveness compared to earlier designs.

Biohybrid Implants: The Next Frontier

Innovations extend beyond merely soft electronics. Rylie Green from Imperial College London drew inspiration from science fiction to envision implants that could actively grow into living tissues. Her team has designed probes coated with a jelly-like hydrogel laden with living neurons that can extend connections into brain tissue, potentially reading brain activity and delivering targeted stimulation for neurological conditions.

Simultaneously, George Malliaras at the University of Cambridge is exploring how to merge living cells with electronic devices to create biologically camouflaged implants. This “Trojan horse” approach could mask the device from the immune system while fostering integration with existing tissues. Initial trials have shown these biohybrid devices can bridge severed nerves, paving the way for innovations in both recording and restoring movement.

The Ambition of Biohybrid Implants

Looking ahead, researchers envision not just bypassing damaged neural circuits but actually restoring them. Startups like Science Corporation are exploring groundbreaking implants that aim to connect to the brain’s complex wiring in ways traditional silicon chips cannot. By fostering connections with genetically engineered neurons, these devices could ultimately restore functions lost due to injury or disease.

Living Electronics: A Paradigm Shift

The potential for “living electrodes,” developed by Kacy Cullen at the University of Pennsylvania, represents the ambition of creating devices from entirely biological materials. Unlike metal electrodes that capture signals from a limited number of neurons, living electrodes can form thousands of connections, enhancing both data transfer and control.

The dream of these technologies stretches beyond medical repair—thought leaders like Cullen express aspirations that these implants could even augment cognitive function. But for now, practical applications are the focus. Current research seeks to develop tools targeting specific neurological challenges, such as balancing dopamine levels in Parkinson’s patients.

Forward with Optimism

Burkhart, after witnessing both the limitations and successes of brain-computer interfaces (BCIs), maintains a realistic outlook on the sector’s progress. He actively participates in a group called BCI Pioneers, striving to ensure that advancements in this field remain practical for users like himself. Meanwhile, the research landscape continues to flourish.

It’s clear that we stand on the precipice of what may be termed the “bioelectronics revolution.” This new frontier may not only lead to improved management of injuries and conditions but could also pioneer profound advancements in human health and wellbeing. The hope persists that these developments will bring transformative change—lifting the burdens of disability and enriching the quality of life for many.
