1) Cancer Spit Test
It is the time to forgo biopsies. Researchers at the University of California-Los Angeles have invented a device that detects oral cancer from a single drop of saliva. Proteins that are associated with cancer cells react with dyes on the sensor, emitting fluorescent light that can be detected with a microscope. Even this formula can be used to detect other kind of diseases.
2) Smart Contact Lens
Glaucoma, the second-leading cause of blindness, develops when pressure is build inside the eye which damages the retinal cells. University of California-Davis developed the contact lenses which contain conductive wires that continuously monitor pressure and fluid flow within the eyes of the persons who are at risk. The lenses then pass the information to a small device worn by the patient; the device wirelessly transmits it to a computer. This constant flow of data will help the doctors better understand and diagnose the causes of the disease. Future lenses may also automatically dispense drugs in response to pressure changes.
3) Speech Restorer
People who have lost the ability to talk, Illinois-based Ambient Corporation have discovered a new "phonetic speech engine" to provide audible voice. Developed in collaboration with Texas Instruments, the Audio uses electrodes to detect neuronal signals traveling from the brain to the vocal cords. Patients visualize sounding out words; then the quarter-size device (located in a neck brace) wirelessly transmits those impulses to a computer or cellphone, which produces speech.
4) Muscle Stimulator
The time taken by the broken bones to heal, makes the nearby muscles to often atrophy from lack of use. StimuHeal, an Israel-based company decodes that problem with the MyoSpare, a battery-operated device that uses electrical stimulators which are small enough to be worn underneath casts in order to exercise muscles and keep them strong during recovery.
5) Nerve Regenerator
Nerve fibers can't grow along injured spinal cords because scar tissue cause a blockage. A nanogel developed at Northwestern University eliminates that hindrance. This is injected as a liquid after which the nanogel self-assembles into a scaffold of nanofibers. Peptides expressed in the fibers instruct the stem cells that would normally form scar tissue to produce cells that encourage nerve development. The scaffold, however, supports the growth of new axons up and down the spinal cord.
6) Smart Pill
California-based Proteus Biomedical has engineered sensors that track medication use by recording the exact time drugs are ingested. Sand-grain-size microchips release high-frequency electrical currents that are received by Band-Aid like receivers on the skin. The receivers also monitors heart rate and respiration and wirelessly transmit the data to a computer.
7) Autonomous Wheelchair
MIT researchers have developed an autonomous wheelchair that can take people at their direction. The chair monitors its environment by listening when the patient identifies locations such as "this is my room" or "we're in the kitchen" and builds maps using Wi-Fi, which works well indoors (unlike GPS). The current model, which is now being tested, will be equipped with cameras, laser rangefinders and a collision avoidance system.
