Working Principles of Microsystems

Acoustic sensors are used to detect

• Sound

• Temperature

• Chemical Compositions

Medical diagnosis uses

• Bio sensors

• Biomedical sensors

• Both these Sensors

Biomedical and biosensors are

• same thing

• Both are different

• Neither of the above

Biosensors Require______to work

• Biomolecules

• Electrochemical Compounds

• Chemical Compounds

Chemical sensors work on the principle of

• Interaction of chemical and electrical properties of materials   

• Chemical and biological interaction   

• Mechanical and Electrical interaction

Any material that has a change of electrical properties after being exposed to particular gases can be used as

• Chemical Sensor

• Biosensor

• Thermal Sensor

Optical sensors work on the principle of

• Input heat generated by light

• Input photon energy by light

• Impact of electrons on solid surface

Pressure sensors work on the principle of

• Deflection of thin diaphragm

• Heating of thin film

• Magnetizing thin diaphragm by the pressurized medium

Deflection of the thin diaphragm in micro pressure sensors is measured by

• Mechanical means

• Optical Means

• Electrical Means

Thermal sensors work on the principle of

• Thermal Mechanics

• Thermometers

• Thermal Electricity
