Medical physics plays an important role in the development of prosthetic limbs and implantable devices. This process is based on the principles of mechanics, biomaterials, and biomedical physics.

In prosthetic design, joint and muscle movement is studied to determine how to mimic natural movement. Light and strong materials such as titanium alloys and carbon fiber are used to provide durability and comfort.

Physical sensors are used to measure pressure and force, helping to improve the balance of the prosthetic limb.

Medical physics also helps integrate limbs with nervous systems using electrical signaling techniques.

As for implantable devices such as pacemakers or cochlear implants, they are designed based on the principles of electricity and magnetism.

Medical physics ensures that these devices are compatible with the body's tissues to minimize immune rejection. It also calculates energy levels and electrical charges that are safe for the body.

It also plays a role in testing the bio stability of implanted devices to ensure they will function for long periods inside the body. In addition, 3D medical imaging is used to design precise devices tailored to each patient's individual anatomy.

Nanotechnology contributes to the creation of smart materials that respond to different body conditions.

Medical physics has made it possible to improve patients' quality of life and increase their independence. This discipline combines physics, engineering, and medicine to provide advanced healthcare solutions.
