MEMS devices for biomedical

What is MEMS?

  • Microelectromechanical Systems
  • Micro: sizes ranging from nm to mm
  • Electro: signal/ control (sense,compute, etc.)
  • Mechanical: structure/functioning(actuate, etc.)
  • System: integration, communicate,control

 

Constraints of Bio MEMS

  • Material requirements
  • Biocompatibility
  • Mechanical compatibility
  • Chemical resistance
  • Polymer MEMS
  • Advantage
  • Biocompatible and biodegradable
  • Better mechanical shock tolerance
  • Low cost
  • Disadvantage
  • Mechanical properties change dramatically over a narrow temperature
    range (low glass transition temperature and melting point)
  • Gas/moisture permeable will need hermetic packaging
