Part A
Brief introduction:
Microsystems are a rapidly developing technology that integrates Micro electromechanical systems (commonly known as MEMS) and microfluidics devices with microelectronics and optoelectronics circuits. Due to increasing demand and opportunities from these fields, universities are introducing or have introduced MEMS/Microfluidics courses to their students at undergraduates and graduate levels. By its nature, the field is multidisciplinary and requires various backgrounds when integrating all components of Microsystems as described above. The current challenges in this area are design, fabrication and testing the microsystem devices. This brings various constraints on both the instructors and the students from the point of teaching and learning aspects. Designing a typical microsystem requires the use of modeling and simulation tools from multi energy domains (circuit simulators, multiphysics analysis, 3D modeling, fluidic flows etc). Fabrication methods have recently been evolved from traditional

Proximity Sensor
A sensor that can be used for detecting the presence of objects surrounding it without having any physical contact is termed as a proximity sensor. This can be done using the electromagnetic field or electromagnetic radiation beam in which the field or return signal changes in the event of the presence of any object in its surrounding. This object sensed by the proximity sensor is termed as a targe
Thus, if we discuss about different types of targets such as plastic target, metal target, and so on requires different types of proximity sensors such as capacitive proximity sensor or photoelectric proximity sensor, inductive proximity sensor, magnetic proximity sensor and so on. The range in which the proximity sensor is able to detect an object is termed as nominal range. Unlike the other sensors, proximity sensors can last for long life and have very high reliability as there are no mechanical parts as well as no physical contact exists between the sensor and sensed object.
NPN sensor
Limit switches are used to detect the presence or absence of an object.
These switches were originally used to define the limit of travel of an object, and as a result, they were named Limit Switch.
switch where a beam of infrared light from the LED illuminates a Phototransistor, causing it to conduct. When an object is moved into the slot between The LED and phototransistor the light is interrupted and the phototransistor switches Off. Opto-activated switches are normally operated in saturation mode to provide Definite on and off signals.
Another common application for slotted switches is to have a rotating disc, with slots or holes around its rim to spin within the light path of the switch, thereby creating a series of on/off pulses that can be used to indicate (and electronically control) the speed of the spinning disc.
Pressure sensor
This Pressure sensor circuit we are going to use Piezo element as a sensor. Because we need to obtain an electric signal from a mechanic signal or force. You might have seen circuits where digital output switches states depend on threshold pressure. But here in this circuit based on the input pressure Output voltage varies. Therefore the results will be Analog in nature rather than the usual digital ones.
