Why Organic MEMS?
14
Performant MEMS devices thanks to specifically designed
functions (actuation, transduction, molecular recognition, etc)
and structures integrated at low-cost
1. Main motivation: low values of Young’s Modulus
Reduced stiffness
2. Polymers are synthesized at low-cost
3. Good processability of organic materials thanks to printing methods (micro
and nano)
4. Large control of: - Optical properties
- Mechanical properties
- Electrical properties
- Chemical properties
A specific function can be accurately tuned
