This article discusses the impact of touchscreen technology on people’s daily lives, which is essential for electronic devices such as smartphones, and the advancement of nanopatterning technology to solve the problem of oil stains during use. It explains how nanotechnology can be used to improve the performance of touchscreens and revolutionize future mechanical engineering and other industries.

Grease can’t keep you from sitting on a thorny seat

This is arguably the golden age of smartphones, and the number of people using them is growing rapidly, as are the number of people using e-readers and tablet computers. It’s hard to find a person who doesn’t have one of these devices in their bag or pocket, and smart devices have become a necessity in modern life. One of the things that makes smartphones especially smart is the ability to use your fingertips to manipulate the screen to select photos and zoom in on them. Touchscreens have also become an integral part of portable electronics, including MP3 players, car navigation systems, e-books, and tablet computers. This trend is expected to continue as mobile devices become smaller and more powerful.
A few years ago, a cell phone manufacturer’s commercial defined the reason why he liked his girlfriend better than the iconic Korean movie star Jeon Jeon-hyun: “Because I can touch her at my fingertips at any time. In many of life’s most precious moments, we touch the world with our fingertips: the last hand we hold with a loved one as we say goodbye to the world, the handshake we share at a reunion after decades, the innocent excitement of our fingertips gently touching while walking with the opposite sex. It’s the most direct and emotional way humans interact with the world, and these touches hold great meaning in people’s lives.
The act of touching the world with our fingertips isn’t just an emotional interaction, it’s also becoming an important component of technological advancement. Emotional engineering, which is gaining traction around the world, aims to more accurately convey and reflect human emotions through the smallest movements and touches of our fingertips. As a result, the demand for electronic devices with touchscreens is expected to continue to grow. However, when using touchscreens, users are often faced with the problem of fingerprints or oils on their hands causing abnormal operation of the device. One of the technologies to solve this problem is anti-fingerprint technology.
Several technologies are being developed to prevent smudges on touchscreens, but one that is gaining traction is Nano Patterning. Nanotechnology is a process that deals with the size of a human hair, which is about one hundred thousandth the size of a human hair, and it plays an important role in designing very small structures and applying them to real-world industries. The semiconductor manufacturing process is also a successful example of using nanopatterning technology. This technology has revolutionized mechanical engineering over the past decade, and has even raised the possibility of converging mechanical engineering with other disciplines. It is now believed that nanotechnology and biofusion, rather than traditional mechanical engineering, will be the key to the future.
The nanopatterning technology used in smartphone anti-fingerprint films is based on a technique called soft lithography. This is an advanced technique that creates microscopic bumps or holes by drawing a desired shape on a metallic material, such as silicon, and then injecting a polymeric material to harden it. The nanostructures created by this process can prevent grease from sticking to surfaces, and could be used in a variety of applications, including greaseproof windows, textiles, and even home appliances.

Emotional fusion of humans and technology

The way we interact with the world with our fingertips isn’t just important for interacting with electronics. In our daily lives, our fingertips are an important means of creating emotional bonds between people. For example, the sense of security that a child feels when holding a parent’s hand or the warmth that lovers feel when they hold each other’s hands represents an emotional connection that goes beyond mere tactile sensations. In this sense, it’s natural for touchscreens to connect with human emotional connections. As technology evolves, it becomes increasingly important to explore these emotional elements more deeply.
This experience of feeling the world at our fingertips is at the core of emotional connection, even in modern technology. Efforts to reduce the inconvenience of handprints and grease stains through nanopatterning technology suggest that technology needs to go beyond mere convenience and connect with human emotions. The electronics of the future will no longer be mere tools, but vehicles that strengthen the emotional connection with their users.

The future of mechanical engineering, converging with nanotechnology

The first decade of the 21st century has seen changes that rival the information and communication revolution of the mid-to-late 20th century. Global economic crises, population growth, environmental pollution, and food issues are facing humanity with new challenges, and new breakthroughs in science and technology are needed. Mechanical engineering, in particular, is pushing the boundaries of its existing limitations based on nanopatterning technology, which represents a key direction for future engineering technology.
Nanotechnology and biofusion can revolutionize not only the medical field, but also many other industries. Just as it’s hard to sit on a thorny seat with grease on it, science and technology will have to overcome uncomfortable realities and continue to advance toward a better future.
