- The MEMS devices such as presuure transducer, micropipes, microactuators, are explained in detail. The structural design and principles are expalined neatly and easily understandable
REPORTdistance
- The report details the implementation of distance measurement system using the ultrasonic waves. As the human ear’s audible perception range is 20 Hz to 20 kHz, it is insensitive to ultrasonic waves, and hence the ultrasound waves can be used for
