BIONICS
Defining ‘Bionics’
Bionics
What Does ‘Bionic' Mean?
Bionics is the merging of man with machine . It is an interdisciplinary field encompassing biology, neurosciences, mechanics, electronics and robotics. Bionics scientists attempt to make devices that interact with human muscle, skeleton, and nervous systems with the goals of assisting or enhancing human motor control that can be lost or impaired by disease or birth defects

TOUCH BIONICS
Touch Bionics is a leading developer of advanced upper-limb prosthetics (ULP). One of the two products now commercially available from the company, the i-LIMB Hand, is a first-to-market prosthetic device with five individually powered digits. This replacement hand looks and acts like a real human hand and represents a generational advance in bionics and patient care. The Touch Bionics i-LIMB Hand was developed using leading-edge mechanical engineering techniques and is manufactured using high-strength plastics. The result is a next-generation prosthetic device that is lightweight, robust and highly appealing to both patients and healthcare professionals. The i-LIMB Hand is controlled by a unique, highly intuitive control system that uses a traditional two-input myoelectric (muscle signal) to open and close the hand’s life-like fingers. Myoelectric controls utilize the electrical signal generated by the muscles in the remaining portion of the patient’s limb. This signal is picked up by electrodes that sit on the surface of the skin. Existing users of basic myoelectric prosthetic hands are able to quickly adapt to the system and can master the device’s new functionality within minutes. For new patients, the i-LIMB Hand offers a prosthetic solution that has never before been available.

Yet, what happens if the experiment grows out of control? These hybrid humans, armed with superhuman capabilities, may no longer possess emotions or a moral conscious. They may no longer possess a soul. The possibility of bionic creatures with superhuman fighting capabilities is absolutely chilling. What happens when a human being stops being human? The answer may not be so environmentally friendly.
Hijacked on the Way to Healing .It's clear that seriously ill patients are being stolen. And we know why they are being. labs are operating in secret. Kidnapping these unidentified patients against their will, to turn them into bionic creatures with unknown powers.
Faster, lighter computers possible with nanotechnology
SMALLER AND LIGHTER COMPUTERS
NO WORRIES OF ELECTRICAL FAILURES.
TINY COMPUTERS.
NVRAM(NON VOLATILE RAM)
Experiment done by MIT
They have made a robotic fish
Component use for Robotic Fish.
A Styrofoam float allows the fish to float
Electrical wires make the connections
A silicone tail provides the swimming force
Lithium batteries provide power
A microcontroller control the robot's movement
An infrared sensor enables the
microcontroller to communicate
with a handheld device
A stimulator unit electrically stimulates
the muscles
ELECTRONICS OF HUMAN BODY
Consider what happens when you lift your foot to walk:
The motor center of your brain sends impulses to the muscles in your foot and leg. The appropriate muscles contract in the appropriate sequence to move and lift your foot.
Nerve cells in your foot sense the ground and feedback information to your brain to adjust the force, or the number of muscle groups required to walk across the surface. You don't apply the same force to walk on a wooden floor as you do to walk through snow or mud, for example.
Nerve cells in your leg muscle spindles sense the position of the floor and feedback information to the brain. You do not have to look at the floor to know where it is.
Once you raise your foot to take a step, your brain sends appropriate signals to the leg and foot muscles to set it down
APPLICATIONS of Biomechatronics
To Heal. By replacing injured body parts with mechanical versions, bionic advancements can significantly improve the lives of disabled individuals.
To Avoid Injury. Bionic technology can also be used to help humans prevent dangerous situations. .
To Defend. Although The Center considers it ethically irresponsible, there are many nations who continue to work toward the development of a biomechanical soldier.
To Entertain. In case we forget, bionics can also provide great joy.
