Micro-electromechanical systems (MEMS) are small devices that integrate mechanical and electrical functions on a single chip, ranging from 1 to 100 micrometers in size. They find extensive applications in automotive systems, medical devices, and various sensor-based technologies, offering advantages like improved accuracy and miniaturization, despite high establishment costs and design complexities. MEMS are poised to significantly impact the future of technology in various sectors, including automotive, biomedical, and communications.
Microelectromechanical Devices And Applications of MEMs
- 2. INTRODUCTION • MEMS is a technology of very small devices. It is a combination of mechanical functions and electrical functions on the same chip • MEMS are made up of components between 1 to 100 micrometers in size. • MEMS are attractive for many applications because of their small size and weight
- 3. What are MEMS? (Micro-electromechanical Systems) MEMS devices sense, think, act and communicate.
- 4. MEMS are constructed on one chip with electrical circuitry for inputs and outputs of the electromechanical components. The interaction of electronics, mechanics, light or fluids working together makes up a micro-electro-mechanical system or MEMS. Include motion, light, sound, chemistry, biochemistry, radio waves and computation, but all on a single chip
- 7. In Automotive Heavy use of MEMS is found in automotive such as in • Air bag systems, • Vehicle security system, • Vehicle dynamic control, • Rollover detection, • Vehicle Navigation Systems, • Automatic door locks • The Sensor Cluster etc.
- 10. MEMS in the Medical Field • A MEMS is a device that can be implanted in the human body. • MEMS surgical tools provide the flexibility and accuracy to perform surgery.
- 11. MEMS AUGMENTATION • Hearing Aids
- 12. • Sight
- 13. • Kidney
- 14. MEMS in the Diabetes patient A) Chemical sensor B) To the patient. C) Measures the blood glucose and a transmitter D) That sends the measurement to the a computer in (A)
- 15. Digital Tattoo Digital tattoo monitors blood below the skin
- 16. • The Heart ( Cardio-MEMS )
- 17. MEMS MICRONEEDLES MEMS enables hundreds of hollow micro-needles to be fabricated on a single patch of area. This needles is applied to the skin and drug is delivered to the body using micro-pumps. Micro-needles small so can easily reach and stimulate the nerve endings.
- 19. Advantages Minimize energy and materials. Improved reproducibility. Improved accuracy and reliability. Increased sensitivity.
- 20. Disadvantages Farm establishment requires huge investments. Micro-components are costly compared to macro components. Design includes very much complex procedures
- 21. CONCLUSION Thus hereby we concluded our presentation in the topic of MEMS which is going to be the future of the modern technical field in the growth of micro sensor based applications such as automotive industries, wireless communication, security systems, bio medical instrumentation and in armed forces.
