In the Güder Research Group, we are mainly motivated by solving problems however, we also understand the importance of exploratory research. Both of these approaches can result in new discoveries and technologies. This is why, we follow both research strategies to address scientific and technological problems of the world.
The primary factors driving adoption of new discoveries by others throughout the world, are the cost and the ease of use of the method, material or the system developed. Affordability and simplicity improve accessibility and minimize the financial barrier to solve problems using science and technology. We therefore, pay particular attention to keep things simple and easy.
Areas of Research
The group has expertise with research and discovery of new materials, development of sensors/actuators and their transformation into useful systems. By covering the entire range of development, we aim to accelerate translation of new technologies (may it be new materials, sensors or actuators) from the bench to the field which is one of the greatest challenges in academic research.
Paper-based Sensors and Actuators
Due to its porosity, high-surface area, printability, and ability to wick water, paper is a widely available, low-cost material that is often overlooked for high-tech applications. We explore the use of paper in building printed sensors and actuators. Diagnostic sensors made of paper can be a viable alternative to centralized lab tests in countries with limited infrastructure for healthcare (e.g., the developing world). These disposable sensors are also ideal for use in agriculture for rapid screening. The paper actuators can be used for automated handling of fluids without human intervention. The paper-based devices can be disposed by simply burning, eliminating the need for special treatment of the biologically contaminated devices.
Wearable sensors allow collection of important data (both physiological and chemical) concerning health and behavior of animals and humans. In our group, we design and fabricate light-weight, flexible and stretchable sensor systems that consist of both conventional and unconventional (such as composite polymer sensors) components that are interfaced with mobile devices such as smartphones and tablets, wirelessly. This feature adds large amount of computation power to the systems built for onsite analytics. It also enables cloud storage and remote access capabilities, a characteristic that’s important for applications regarding digital health and agricultural management.
New Materials and Methods for Printed Devices
We are interested in the synthesis of functional inks and discovery of new methods and tools that enable low-cost fabrication of new classes of printed sensors and actuators. We are particularly interested in the synthesis of colloidal inks using nanoparticles and nanowires.
Microfabricated Semiconductor Biosensors, Gas Sensors and Devices for Controlled Release
For applications requiring miniature devices with high precision and low power, microfabricated semiconductor devices have unmatched advantages over systems produced by other technologies. We build various sensors and actuators using both conventional (top-down) and unconventional (bottom-up) microfabrication methods.
