TSUFI PREM Research Areas
Next-generation wearable electronics and biosensors have important applications in medicine, the environment, and biology. Realizing these technologies require materials that are simultaneously deformable, selectively sensitive to their environment, and electrically active. Piezoelectric polymeric thin films and nanofibers are excellent candidates for these applications because they are flexible, chemically inert, can be doped, and have a high surface-to-volume ratio suitable for specific sensing applications. The grand challenges the TSUFI PREM addresses comprise two thrusts:

Thrust I:  Low-dimensional (NFs and films) polymeric materials synthesis and characterization
Lead:  Prof. Richard Mu
Co-lead: Prof. Frances Williams

Establish design rules of materials synthesis to optimize the functionality of ferroelectric polymeric materials and develop scalable manufacturing through fundamental understanding of the basic science and physical materials processing.

Thrust II: Production and modeling of heterostructures containing 2D materials
Lead: Prof Ranganathan Parthasarathy

Integrate the materials with other deformable materials through interface engineering to achieve nanosystems and nanodevices whose properties and functionality are far beyond that of the single materials alone. 2D materials, for example, can serve as excellent deformable electrodes and be used for high-mobility electronics.
