Insect repellent device

2022: Technology Announcement

On October 11, 2022, the Martin Luther Halle-Wittenberg University (MLU) in Germany announced the development of a new technology for creating devices for repelling insects - primarily mosquitoes: we are talking about a special method of 3D printing.

The essence of the invention is as follows. First, the active ingredient is "encapsulated," after which an accessory for repelling insects is created from a biodegradable polymer material using 3D printing. It may have, for example, the shape of a ring to be worn on a finger. If necessary, the product can be given a different shape.

For their experiments, the researchers chose a repellent IR3535 develop Merck, which is also known as ethyl butylacetylaminopropionate. This substance does not irritate the skin and has been used around the world for many years. As a spray or lotion, the IR3535 lasts for several hours. The technology proposed by MLU specialists provides protection against mosquitoes for at least several days.

Шаблон:Quote 'The main idea is that the remedy constantly evaporates and forms a barrier to insects, the authors of the work say. The rate of evaporation of the repellent depends on various factors, including the temperature, concentration and structure of the polymer used. Experiments showed that at 37 ° C (approximately normal human body temperature), the agent would last longer than a week. However, while the rings and other wearable products made using the proposed technology exist only in the form of prototypes. Developers will have to conduct a number of additional studies to determine the effectiveness of the method in real conditions. Based on the results obtained, it may be necessary to optimize the structure of the encapsulating^[1]
