Scientists reproduce the "half-spiral" shape in springs or will help nanodevice development

Researchers at Harvard University obtained some interesting findings while working on project research. The team was preparing to create a spring for an imaging project. As a result, it was discovered during the process that the spring had an unusual "hemihelix" in its shape.

After this shape appeared, the team was eager to find out whether the occurrence of this shape was a random event or was controlled by certain special factors. Finally found in the experiment, to achieve this structure is completely controllable. The experimental content includes the use of rubber strips.

The team also used numerical simulations in their research. Now that the research team has been able to reproduce this semi-spiral shape very accurately, the researchers say they may be able to simulate this geometry in new molecules. Nanodevices such as similar sensors, resonators, and electromagnetic wave absorbers can provide performance enhancements.

The semi-helix discovered by the researchers is accompanied by multiple "inverted" properties. When an "inversion" occurs in the spiral process, the direction of the spiral changes regularly. Two rubber strips of different lengths are made into springs, the shorter one is stretched to the same length as the longer one, and the two can be twisted together. The researchers found that when the length of the rubber strip is much greater than its width, a spiral is generated, and it is also found that the corresponding aspect ratio can periodically generate such a half-helix.
