Research
Anupama’s thesis work includes the design, fabrication and testing of an implantable BioMEMS sensor capable of intracellular neuronal recording. This work gives the first evidence of intracellular interrogation by an integrated implantable MEMS sensor. The sensor comprised of a high aspect ratio, sub-µm tip needle electrode integrated with a flexible polyimide-aluminum-polyimide interconnect. The success of this prototype is a major step toward self contained implantable devices suited for intracellular neuronal recording from freely behaving animals. This work involves significant inter-departmental collaboration.
She has investigated biomaterials developed at The University of Washington Engineered Biomaterials Center (UWEB) as possible coatings for implantable neural electrodes. Application of these biomaterial coatings can be easily integrated with standard microfabrication processes.
The last part of her thesis is in collaboration with the Indian Institute of Technology (IIT Bombay). Here she has developed a technique for vapor-liquid-solid growth of needle arrays by hot-wire-chemical-vapor-deposition (HWCVD) at low substrate temperature. This low temperature growth technique has the potential for integration of CMOS circuitry and biomaterials like polyimide with neural electrodes. Needle arrays grown by this technique can potentially enable high throughput neural recordings. She has independently initiated and developed research collaborations between IIT Bombay and University of Washington (2007-present).
