Overview

From need to functional engineering system.

The project evolved an established rigid device toward enhanced planar and anatomically conforming flexible PCB architectures, combining sensing-array redesign, electronic miniaturization, mechanical integration, characterization, and clinical evaluation.

My contribution

  • Designed and assembled successive rigid and flexible PCB iterations.
  • Expanded the active sensing area by 11.23% and geometrically validated the sensing matrix.
  • Developed compact and anatomically conforming architectures for improved intra-oral fit.
  • Created test methods and analysis workflows for device characterization.
  • Supported IRB-approved evaluations and quantitative rehabilitation analysis.
