Damping for perforated mass

i m desinging single axis accelerometer for out of plane axis using metals mumps. the damping formula which u have given, gives me very high value of damping. the system is overdamped with dampng co efficeint of 400. my first question is how to calc

• damping co efficient

Where can I get a pulse forming network, a pulse laser head, mems mirrors, and galvano mirrors?

If you know of any store, website or other place tat sells 1 of these items, I'd greatly appreciate it! Thanks!

• galvano mirrors
• MEMS
• mems mirrors
• pulse laser

How do i calculate the normalized power for an optical mems based pressure sensor?

I need to plot the output characteristic of a ring resonator(Optical-MEMS) based pressure sensor). For that i need the formula to calculate normalized power as my 'y' axis variable. The 'x' axis variable is wavelength in microns. I can make design as

• Optical-MEMS
• pressure sensor

what is the subsitute for micro-niddle ?

Recently micro-niddle have been in the limelight for percutaneous drug delivery in medical and cosmetic field. But, micro-niddle have an inevitable disadvantage that caused pain. For the purpose of percutaneous drug delivery, what is the substite
