CBM352 HUMAN ASSIST DEVICES L T P C 3 0 0 3
Human Assist Devices is an interdisciplinary subject focusing on the design and application of devices that assist, rehabilitate, or enhance human physical and sensory functions. It integrates biomedical engineering, electronics, mechanics, and control systems.
The syllabus covers classification of assistive and rehabilitative devices, including orthotic, prosthetic, and therapeutic systems. Biomechanics and human motion analysis are introduced to understand body–device interaction.
Sensors and actuators used in assistive devices, such as force sensors, EMG sensors, and smart materials, are studied. Signal acquisition, conditioning, and processing for physiological signals form a core component.
The course includes control strategies for assistive systems, including feedback, adaptive, and intelligent control. Human–machine interfaces (HMI) and ergonomics are emphasized for safety and comfort.
Applications such as prosthetic limbs, exoskeletons, mobility aids, rehabilitation robots, and wearable assistive devices are discussed. Ethical issues, safety standards, and future trends in assistive technology are also covered.
Human Assist Devices plays a vital role in improving quality of life and supports advancements in healthcare and rehabilitation engineering.
COURSE OBJECTIVES:
● To study the role and importance of machines that takes over the functions of the heart and lungs,
● To study various mechanical techniques that help a non-functioning heart.
● To learn the functioning of the unit which does the clearance of urea from the blood
● To understand the tests to assess the hearing loss and development of electronic devices to compensate for the loss.
● To study about recent techniques used in modern clinical applications
