Stroke is one disease that ranks top on the list of “most dangerous threats to human health”, but pity that there was no completely useful ways to cure or monitor the stroke, until these days when scientists from Mayo Clinic in Florida have developed the wearable head patch. The device is known as near-infrared spectroscopy (NIRS), and it will be attached to a patient’s forehead like a sticker to monitor the potential advent of another stroke through the simple act of shining light through the brow skin. It will measure blood oxygen levels in the brain, based on which a doctor can determine whether or not there’s a possibility of another stroke. Compared with other products that are usually big and heavy, the device is really smart for everyday use.

How to effectively treat burns with fewer efforts? It seems that scientists from all over the world are offering us with different solutions, and the Biomask is rightly the one put forward by the USA military. The mask is built with sensors, actuators and a regenerative elixir inside, which would help your face regain mussing facial tissue within several months. The biomask for facial faces is expected to hit the market in 2017.

MITI System’s micro-needle is a medical instrument that can function in both beauty and medical fields. It is perfect to make beauty instruments that are widely used by skin-care specialists with the micro-needle, which will not only ensure a better absorption of cosmetics into skin, but solve skin problems like age spots, blemish and others. On the other hand, the micro-needle would benefit to the medical fields too, where it can be used as a delivery system of things such as vaccine, hormone, insulin, protein treatment products.

Researchers from the Purdue University have created a Bass-powered medical implant that can utilize sound waves as an energy source. This new pressure sensitive microelectromechanical system has a vibrating cantilever that’s receptive to sound within the 200Hz to 500Hz frequency spectrum. By applying such smart technology into producing medical implants, you can then get some better appliances that can convert the low-frequency vibrations into energy, so as to power themselves automatically.

There’s an exponentially increasing demand for a newer and better way to deliver drugs inside the stomach, and the urgent need now resulted in the development of this hydrogen-powered microrockets that powered by microbubbles and steered by micromagnets. The rocket is very tiny, just micrometers long while consists of polymer tubes packed with zinc. When the zinc comes in contact with an acid inside your stomach, it soon reacts to release hydrogen, which will then push the rocket forward at a top speed of up to 100 body-lengths per second. To get a good control of the fast-moving rockets, researchers have coated them with a layer of magnetic material on the outside, so that these rockets can be started, stopped or steered via an external magnet. Currently the level of the control is announced fine enough to enable the microrockets to pick up and drop off little cargo modules that will eventually contain drugs, so quite possibly we’ll soon see them widely used in hospital to cure our diseases more efficiently.

The next generation of capsule camera is already here: a little cam developed by scientists from the Brigham and Women’s Hospital, which can work by receiving magnetic instructions from the MRI that steers a rudder like motor. As the device is wirelessly guided, it will then eliminate the need for an invasive tether guidance system and also reduce the discomfort of patients. It hasn’t been tested yet in the human body, but it has been tested in water, so we believe the human trials shouldn’t be far behind, and the day to use it will come soon.

Coming from Hannes Harms, the “Sono” is a concept of a mobile and wireless sonography system. It enables both an uncommitted handling of the probe and an unlimited connectivity to almost all already-installed screens in hospitable wirelessly, making it quite ideal as a portable and versatile diagnosis device for doctors.

After a whole day spending with the computers, our eyes usually get dry and tired, but fortunately that problem can be solved by the Dry Eye Relief Goggle. To use it, you firstly need to warm the gel packs in a microwave and then place them inside the goggle, which would stimulate tear production after you’ve worn the goggles for 15 to 20 minutes. Additionally, the goggle can form an impervious, 360° seal to prevent air, dirt or pollen, and thus it could be quite useful to people suffering from lagophthalmos too.

Electronic diabetic contact lens is a development collaborated by scientist from University of Washington and Microsoft Research, which is announce to ensure a wireless monitoring of the wearer’s blood sugar levels. The contact lens utilizes an enzyme-based electrochemical process sensitive to glucose, as the enzyme interacts with the tear fluid, certain measurements are then made and reported to the users.

Recently, an intelligent smart bandage is developed by researchers at University of Illinois Urbana-Champaign that can promote angiogenesis and guide exactly where the vessels should go. It is built of layers of a hydrogel made of polyethylene glycol and methacrylic alginate. The bandage is porous and allows small molecules to leak through while directing the flow of larger molecules. Several experiments are conducted on the surface of a chicken embryo, revealing that the network of new blood vessels mirrors the patterns of the channels of the bandage.  There are several potential applications for this intelligent bandage including directing the growth of blood vessels around a blocked artery and normalizing blood vessels that feed a tumor to improve the delivery of anticancer drugs and so on.

The Plasma Toothbrush invented by scientists at the University of Missouri is a new type that disinfects and cleans out cavities, kills bacteria and forms a better bond for the fillings without resulting in any feeling of pain. It features a high efficiency too, accomplishing the dental filling within less than 30 seconds while still ensures the fillings 60 percent stronger than common ones. The Plasma Toothbrush is expected to be arriving in 2013.

The cold winter makes you suffer but you don’t know why? Well, according to scientific researches, the reason that people feel lack of energy in winter is because they lack enough bright white daylight. So in order to help people get fully energized in winter, the SEQINETIC “sun” glasses are created, offering bright light to beat the winter blues. But will that really work? Let those who have tried the glasses to tell us the answer then.

Snoring is something like smoking, as it not only destroys the health of the person who makes it, but brings bad influences to people around. We need to stop the snoring, and obviously the robotic bear pillow is a possible method. It would paw at your face if you’re snoring, encouraging you to move your head from side to side and thus to stop snoring. Will the robotic bear pillow really work? Let’s go through the video to see its performance then.
