PhD Thesis: Fabrication of Porous Elastomer and Its Applications

Guide: Prof. Dipti Gupta, Plastic Electronics and Energy Laboratory, Department of Metallurgical Engineering and Materials Science, IIT Bombay

Description: Sensor fabrication with repeatability and sensitivity is critical when addressing the fabrication costs for large-area applications. The effectiveness of electronic circuitry relies on the sensor capability. In this context, developing a low-cost large area-scalable fabrication method involving biodegradable materials is devised through this thesis with enhanced sensitivity. A porous Polydimethylsiloxane is fabricated with dimensional scalability for realizing tactile sensors as well as energy storage. A readout circuit is designed for real-time interfacing with humans. The developed procedure is adapted to patterned sensor fabrication as well via photolithography.

Techniques used:

  • Analysis of SEM, FTIR, FDXM, EDX, TEM, XPS, Optical profilometry, UV Vis spectroscopy, Dielectric Broadband spectroscopy, Capacitor CV, and Raman spectroscopy
  • Electronics device Tools: TCAD Medici, TCAD Sentaurus Structure Editor, TCAD SProcess, PSpice
  • Wet bench expertise: synthesis of elastomer sponge, photolithography, proximity Nanopatterning, metal nanoparticle synthesis, graphene, and its composites
  • Device fabrication: Clean room practice, assembly of electrical connections for complete device fabrication
  • Device characterization: electrical characterization using Keithley 4200, mechanical characterization using MARK 10 ESM universal tensile measurement system
  • Lithography techniques: UV lithography - double-sided aligner, MJB4 exposure systems
