INTELLIGENT led strip | The test

We live in a world where everything is “smart”. Advances in computer technology, nanotechnology and electronics have made great advances possible. A multitude of devices that previously lacked functions or intelligence now have them. This has also had repercussions in the health sector, with a multitude of new devices for early detection of diseases and infections.

Bandages, or plasters, are also benefiting from this type of technology, with the incorporation of some sensors and circuitry that will now make them more intelligent. They will be able to detect problems in wounds and act before it is too late.

It is true that most heal through a natural process without intervention. And they usually heal quickly, within the first 3 weeks. However, in some people with blood clotting problems, platelet problems, diabetes, or infections, this can cause the healing period of a simple wound to lengthen or become a nuisance.

LED strips go beyond lighting, moving between the ornamental and the functional. And it is that they have the power to set a room and decorate it, but also, placed around a screen, they are able to achieve a more immersive experience in both content viewing and gaming. If you are thinking of buying a LED strip, this buying guide will help you choose the model that best suits your needs and budget.

The first thing to think about is what length of LED strip we need, since this answer will depend on the elements that make up the installation. In fact, if we want to mount a very long strip, the power supply voltage required will be decisive.

The usual is to find models of 5, 12 and 24 Volts, which work with DC direct current, although there are also 220V models that work with AC alternating current. While the former require an AC-DC power supply that transforms the characteristics of domestic electricity to those of the LED strip, the latter can be connected directly.

The Smart Bandage is a creation of professors and graduates of the University of Rhode Island in the United States. There they have managed to develop a type of bandage -applicable to band-aids- that can detect infections and prevent further damage.

The concept was born thanks to the research of chemical engineer Daniel Roxbury, who works at the aforementioned University of Rhode Island, and has achieved it by adding a specific type of nanosensors together with the textile fibers of the traditional bandage. In doing so, he has achieved a non-invasive system that can locate and control an infection in a wound.

“The single-walled carbon nanotubes within the bandage will be able to identify an infection in the wound by detecting concentrations of hydrogen peroxide,” said Professor Roxbury. The main challenge was to create a biocompatible material that would respect the work of the nanotubes.

As your baby grows, interaction with other babies becomes very important. But the truth is, you are your baby’s favorite “little friend”. You’ve probably seen that when you’ve made a puppet dance in front of your baby’s face, the baby’s reaction has been to snatch it out of your hands and put it in his or her mouth. Or he has probably ever squealed with delight when you leaned over to him and said, “I’ll get you!”

These interactions help the baby learn language, social relationships, and cause-and-effect. Once babies begin to understand how things relate to each other within the environment and know what they taste, smell and sound like, and how they feel to the touch, they are ready to move on to the next stage of development: understanding how they work.

This type of play lays the foundation for the play you will do during preschool. Using the oven timer on a toy kitchen or sounding the siren on a toy fire truck means your child has a greater understanding because he now understands that each item has a different function.
