Group Vision
The Transient Sensory Interface Group, led by Dr. Roghaieh Parvizi, is dedicated to advancing the science of soft polymer printed electronics, with a central focus on designing biodegradable and transient soft materials for next-generation printable sensory systems.
At the heart of our research lies the development of innovative soft polymer composites that serve as the foundation for implantable and wearable devices. These sensory systems are engineered not only to function as stimulators—evoking targeted neural responses—but also to record neural signals and investigate the influence of sensory inputs on brain states and cognitive functions. Our multidisciplinary approach seeks to unlock new possibilities in interfacing electronics with biological tissue in a sustainable and transient manner.
Our vision is realized through three core pillars:
- Design of Novel Biodegradable Polymer-Based Composites: Creating advanced materials that combine biocompatibility, tuneable degradation, and optimal performance for use in transient electronic devices.
- Innovative Additive manufacturing: Light Processing-Laminating Printer for Large-Area Bioelectronics, A transformative invention for sustainable, scalable, and high-performance bioelectronics manufacturing.
- Manufacturing of Large-Area Printed Electronics: Pioneering scalable fabrication methods using soft polymer printing techniques, allowing the production of complex, high-resolution sensory systems suitable for biomedical and environmental applications.
- Performance Evaluation Under Degradation Conditions: Testing and evaluation of printed sensory devices during their degradation process, in accordance with established scientific and regulatory standards, to ensure their reliability, safety, and functionality in real-world scenarios.
Through these initiatives, the Transient Sensory Interface Group aims to lead the way in sustainable bioelectronic technologies, transforming healthcare, neuroscience, and wearable sensing while minimizing environmental impact.
Research Projects Overview
Current Projects
1. Digital Light Processing Printer: In my reaserch team we are fabricating an additive manufacturing, commonly known as 3D printing, involves creating objects layer by layer. In DLP 3D printing, a digital light source selectively cures liquid photopolymer resin to form each layer according to the digital design.
2. We are developing transient, conductive materials for fabricating flexible brain electrodes via 3D printing. These biodegradable devices are designed for short-term neural recording or stimulation and eliminate the need for surgical removal. Using extrusion- and light-based 3D printers, we produce high-resolution, customizable structures with tuneable conductivity. Our goal is to create biocompatible, dissolvable neural interfaces that align with the next generation of bioelectronic medicine, offering safer and more sustainable solutions for temporary brain-machine interactions.
