Revolutionizing Neural implants: How PDMS Coatings Are Extending the Lifespan of Silicon Chips
The human body is a marvel of nature, but it’s also a harsh environment for foreign materials. For decades, scientists have grappled with the challenge of creating durable neural implants that can withstand the corrosive conditions inside the body. Now, a groundbreaking study led by Dr. Vasiliki (Vasso) Giagka and her team at the Technical University Delft has unveiled a game-changing solution: PDMS elastomers.
Published in Nature Communications,this research not only addresses the durability of silicon-based neural implants but also opens new doors for their submission in treating brain diseases like Parkinson’s and clinical depression.
The Challenge: Durability in a Corrosive environment
Neural implants, which contain integrated circuits (ICs), are essential for studying the brain and developing treatments for neurological disorders. These tiny devices electrically stimulate, block, or record signals from neurons, offering hope for patients with conditions that were once considered untreatable.
However, the body’s internal environment is far from forgiving.”Miniaturized neural implants have enormous potential to transform healthcare, but their long-term stability in the body is a major concern,” explains Vasso Giagka.To tackle this issue, the team focused on silicon ICs, which are prone to degradation when exposed to bodily fluids. Their solution? Coating the chips with polydimethylsiloxane (PDMS), a soft elastomer that acts as a barrier against corrosive elements.
The Breakthrough: PDMS as a Protective Shield
The researchers conducted accelerated in vitro and in vivo studies over one year, testing chips from two different manufacturers. They created two regions on each chip: a bare die region and a PDMS-coated region.
During the in vitro study, the chips were soaked in hot salt water and exposed to electrical direct currents. Remarkably,the PDMS-coated regions showed only limited degradation,while the bare regions suffered significant wear.
“We were all surprised,” shares Kambiz Nanbakhsh, the study’s first author.”I did not expect microchips to be so stable when soaked and electrically biased in hot salt water.”
This finding highlights PDMS as a highly suitable encapsulant for long-term implantation, ensuring that neural implants remain operational for months or even years.
Implications for the Future of Neural Implants
The implications of this research are profound. By enhancing the durability of silicon ICs, scientists can now design miniaturized neural implants that are not only more reliable but also less invasive.
“Our findings demonstrate that bare-die silicon chips, when carefully designed, can operate reliably in the body for months,” says Giagka. “By addressing long-term reliability challenges, we are opening new doors for miniaturized neural implants and advancing the development of next-generation bioelectronic devices in clinical applications.”
This breakthrough coudl revolutionize treatments for brain diseases, enabling chronic neuroscientific research and the development of brain-computer interfaces that were once the stuff of science fiction.

The Breakthrough in Neural Implants: How Silicone Encapsulation is Revolutionizing Brain-Computer Interfaces
In the ever-evolving world of medical technology, the quest for durability and reliability in neural implants has been a persistent challenge. Enter silicone encapsulation—a groundbreaking innovation that promises to redefine the future of brain-computer interfaces (BCIs) and medical therapies. A recent study published in nature Communications by researchers at Delft University of Technology has unveiled the transformative potential of this technology,offering a glimpse into a future where neural implants are not only more effective but also longer-lasting.
The Lifespan Challenge in Neural Implants
Neural implants, which bridge the gap between the human brain and external devices, have long been plagued by one critical issue: degradation. Over time, the harsh biological environment of the human body can corrode these delicate devices, rendering them ineffective.This has been a significant barrier to the widespread adoption of BCIs and other implantable technologies.
As the study’s lead researcher,Vasso,explains,”This work reveals the critical role of silicone encapsulation in shielding implantable integrated circuits from degradation. By extending the lifespan of neural implants, our study opens up pathways to more durable and effective technologies for brain-computer interfaces and medical therapies.”
Silicone Encapsulation: A Game-Changer
Silicone encapsulation acts as a protective shield, safeguarding the delicate circuitry of neural implants from the corrosive effects of bodily fluids and tissues. This innovation not only enhances the durability of these devices but also ensures their consistent performance over time.
Kambiz, another key contributor to the study, reflects on the meaning of their findings: “This was a long examination, but hopefully results will be useful for many.” Indeed, the implications of this research extend far beyond the lab, offering hope to patients relying on neural implants for conditions such as Parkinson’s disease, epilepsy, and even paralysis.
