Biomedical Engineering & Biomechatronics Provide Solutions Such As Cochlear Implants To Those In Need

Mechatronics is the scientific word for the reverse engineering and/or copying of biological functions of an organism used in various appliances that today dot the landscape of living human beings.

Artificial
intelligence is one such example, where instead of following repeated
iterations of a particular code, the system taps into another source, and then
tries to perform a different iteration; this is based on fuzzy logic. Fuzzy
logic is something that humans have. We perform differently at different times
on the same topic we are working on.

We
get input from our skin, our five senses, and also from the subconscious part
of the brain, where our previous history of what we observed, learned and
unlearned is stored in vast numbers, and it is triggered by a part of the brain
which controls these memory banks. Similar experiments have been used in robots
to see whether they can themselves use repositories of information stored, and
whether the software for them can pick up random sequences of information, and
work on them. It has succeeded to some extent, but a lot more needs to be done.

Within
the field of Mechatronics, lies the field of Biomechatronics, which is more
concerned with the reverse engineering of the molecules and biological
structures to help those in distress such as those with severed limbs,  pathological loss of hearing, sight, and so
on.

For
those with severed limbs, often surgical intervention has helped to restore the
limb back to near normal use. Here’s where the biological science, the medical
science and the informatics disciplines merge. The incorporation of a
microprocessor within the severed and reattached limb enables the person to get
a near full use of that severed limb. All this has been possible due to the
interaction between the three disciplines. More such research is leading to
newer developments.

For
instance, artificial hearts are now being considered and are being tried out in
research in ‘dry labs’ where only simulation is being done,  to see whether that artificial heart can
really function or not.

A
more successful example of biomechatronics is the use of the cochlear implant
which enables a nearly deaf person or even a blind person to get signals which
can be used to restore part of the hearing or give enough signals which enable
them to hear sounds, and signals that help them avoid colliding with object in
their way.
