Top 8 Most Fascinating Inventions Around the World

Tights have long been a staple in women's wardrobes, but they are so prone to tearing that fashion enthusiasts often recommend wearing gloves to put them on. Katherine Homuth, the founder of Sheerly Genius, thought it was ridiculous that while many wild technologies have been created, this basic issue remained unsolved. Sheerly Genius was founded to tackle this problem.

The result? Sheerly Genius created a line of soft, comfortable tights made from fibers used in bulletproof vests and climbing gear, which are 10 times stronger than steel. Homuth claims, 'Basically, they can't be destroyed' (the product has been tested by stretching and cutting with scissors). These tights are significantly more expensive than traditional ones, but many women are willing to pay the price. While regular tights may rip after one or two wears, Sheerly Genius tights can last up to 50 uses.

Imagine never having to squint under the harsh sunlight or experiencing eye strain after hours of working under fluorescent lights. This is the promise of Acuvue's light-sensitive contact lenses, developed in partnership with Transitions Optical to correct vision and adjust to light sensitivity.

Each lens contains a light-sensing filter that automatically adjusts the tint to either darken or lighten depending on the lighting conditions, providing optimal comfort. David Turner, the head of research and development for contact lenses at Johnson & Johnson Vision (the parent company of Acuvue), explained that they had to overcome significant technological hurdles to make this possible.

While Gravity didn't invent the concept of weighted blankets, which are known for their calming effect on the nervous system, they were the ones who successfully marketed the product to a wide audience. These blankets weigh approximately 10% of the user's body weight and contain plastic beads that apply gentle pressure on specific pressure points of the body, helping to relieve stress and anxiety. Co-founder Mike Grillo believes that the success of the product is due to its thoughtful design (the Gravity blanket looks more sophisticated than earlier versions) and its timely release to the market.

This worker protection device helps identify if employees are at risk of serious injuries caused by spinal pressure or related issues. Known as the 'Fuse Risk Management Platform,' this device, created by StrongArm Tech, enables employers to safeguard workers who are more prone to injury, thus protecting their bottom line (According to statistics, severe workplace injuries and accidents cost U.S. companies approximately $59.9 billion annually).

Since its launch in April 2018, the Fuse device has been used by over 10,000 workers, including employees from 10 companies on the Fortune 100 list. Jack McCormack, the customer manager at StrongArm Tech, said, 'Just like Nike and Under Armour create the best products to enhance athletes' performance, we are doing the same for the people who are the backbone of the economy.'

Smoke is a silent killer worldwide. A significant amount of smoke comes from automobile emissions and industrial facilities, leading to thousands of premature deaths from respiratory diseases globally. 3M, a Minnesota-based manufacturer, has created a roofing material that, when exposed to UV rays, breaks down NOx particles in smoke into water-soluble nitrate ions (NO3) that can be washed away by rain, helping to reduce air pollution.

One of the leading roofing manufacturers in the U.S., Malarkey Roofing, became a customer of 3M and incorporated these smoke-filtering particles into all of their roofing materials in 2018. According to 3M's estimates, Malarkey's products reduce smoke levels equivalent to 100,000 trees.

For the visually impaired, everyday tasks like sorting mail or doing household chores can be daunting. But what if they could 'borrow' someone else's eyes to see? This is the concept behind Aira – a service that allows users to subscribe and connect to live video feeds from their smartphone or Aira’s exclusive glasses, which stream their surroundings to an on-demand 'agent' for assistance.

These agents are available 24/7, viewing the video feed in real-time, answering questions, describing objects, or guiding the user through movements. Greg Stilson, a visually impaired individual, used the service for a year to navigate airports before agreeing to join Aira as the product manager. 'That year was the least stressful of my life,' he shared.

Nearly 48 million Americans suffer from hearing loss to varying degrees. While hearing aids can offer significant benefits, some individuals avoid wearing them due to aesthetic concerns. Christian Gormsen, CEO of hearing aid company Eargo, states, 'There is a lot of stigma surrounding hearing loss,' which is why his company spent 8 years designing a compact, discreet, rechargeable hearing aid for those with mild to moderate hearing loss.

Traditional hearing aids often wrap around the ear and require multiple visits to an audiologist for fitting. Eargo Max, on the other hand, fits comfortably inside the ear and can be purchased online with expert consultation. Customers have embraced the product with positive feedback.

Currently, over 3 million people in the U.S. rely on wheelchairs for mobility. However, there has been little innovation in this area, with most wheelchairs being bulky and difficult to navigate across various terrains. Whill, a company specializing in personal electric vehicles, has introduced the Model Ci, featuring omni-wheels—wheels with small discs around the edge that allow for smooth movement in any direction, including sideways.

The Model Ci can travel up to 16 km, effortlessly overcome obstacles as high as 5 cm, and navigate easily in tight spaces. It can also be disassembled in just a few minutes, making transportation simple and convenient.
