Smart sensors begin to be part of portable devices that some have already introduced into their body, such as defibrillators (to prevent cardiac arrhythmias) and neurostimulators (which are used to treat movement disorders, or chronic pain, or anal and urinary incontinence). Finally, the development of intelligent prostheses will be realized, which, connected to our brains, will replace damaged or amputated limbs, or artificial eyes that will allow us to see in those cases of peripheral blindness (due to eye damage).
The last challenge throughout this century will be the integration of nanotechnology in our body, that is, implanting particles that have a size in the nanometer range in our body, with the aim of supplanting the function of damaged cells.
What is certain is that to a greater or lesser extent, in the future, the human body will be fused with different levels of technology.
