Engineering Engineering is the science and

art of applying scientific andmathematical principles,experience, judgment, andcommon sense to design things

that benefit society. If people have built it, grown it,moved it, or launched it intospace, you can be sure that

engineering had something todo with it.

Micro-Electro-Mechanical Systems (MEMS) is theintegration of mechanical elements, sensors, actuators, andelectronics on a common substrate through the utilization ofmicrofabrication technology or microtechnology.

What is MEMS?



36/74


What is BioMEMS? BioMEMS is a subset of MEMS technologies

Many MEMS technologies can be used for BioMEMS Bio includes:

Cells

150-300A for monopolar and bipolar stimulation, respectively. Neural response data indicates a strong dependence on

perimodiolar placement of the array. Back voltages are consistent with operation from 3V supplies

delivering 1mA and 40nC.
