My research is in the area of advanced neurotechnology especially for scientific applications, and one really challenging application is mapping the nervous system. To play in this field, innovation can come in many forms including reduced tissue reactivity, improved electrical performance, or improved mechanical properties. In previous publications, I showed that size of the sensor does matter, and it is important to make cellular-sized device dimensions to keep neurons close to the sensor. Regarding electrical performance, our students are continuing research in new materials and new processes to ensure the highest insulation of passive and active components. We are also designing new circuit architectures to enable higher density, low-noise front-end amplification. And the mechanical properties must be optimized for the application at hand. We are developing ultra-flexible surface sensor arrays, stretchable surface arrays, and stiff but ultra-fine penetrating arrays.
Euisik Yoon, the Director of the Integrated Microsystems Lab, and I are leading several projects under the Brain Initiative focused on high-density optoelectrodes. IPAN, for example, is an international collaboration with other leading neurotechnologists that will co-develop a new generation of neural probe platforms. Other related projects I am helping to lead include a peripheral organ mapping array with the pNeuroLab, and an ambulatory EEG system with the HNL.
To accomplish our goals, our laboratory uses MEMS, integrated circuits, new fabrication methods, and novel packaging in our sensor and actuator systems. We are building amazing technology at University of Michigan in the greater effort to map the nervous system.
We are always interested in talking to students and researchers who want to contribute to this cross-disciplinary research!
