1- what is the meaning of sensor evaluation?? 2- how to evaluate the sensor?? Size—Sensitivity—Robustness--Standardization--Stability- Reliability--Frequency Response & Dynamic Range-- Economic Considerations--Safety Issues--Quality Control & QA--Safety Issues 3- life application ((baby incubator)) 2

 Is it will be work rightly in these condition??  How is it work ??  What are the specification of this sensor ??  Is it will be suitable ?? Simply>>>  It is the important and only way to know and to select the the suitable sensor in suitable place. 3

 Reliability.. Is it will be load these conditions Threshold voltage....thermal stress... ESD sensitivity... 4

 Frequency Response... How is the shape of response for the input and what is signal output shape>>> damped- under damping –linear-over damping 5

Dynamic Range... what is range we need to apply in it?? in the sensing of the human organs or more or down Human Hearing Range Frequency is measured in terms of oscillations of these bones, per second. The unit of frequency is hertz. Typically, 1 Hz = 1 cycle/second 20 Hz to 20 kHz (20,000 Hz) 6

Power Consumption Active implantable devices >>Battery-operated>>self dependant from sun energy 7

 Size… Miniaturization is becoming a trend in sensor design, especially in biomedical applications scopes with different pore sizes of 5 μm, 20 μm, and 30 μm was applied and the effects of humidity on sensor  Sensitivity..Stability.. Robustness..  =the slope of output to input. The higher the slope, the more sensitive is the sensor =How it can be far from the different divisions = the degree to which a system or component can function correctly in the presence of invalid inputs or stressful environment conditions  QC & QA Ease of maintenance and calibration in line production  Economic Considerations 8
