Scenarios for the Future of Wearable Devices and Next-Generation Semiconductors: Fine Copper Powder as a Key Material Accelerating IoT and an Energy-Efficient Society

As we move into a world where everything is connected—the era of the Internet of Things (IoT)—the wearable device market continues to grow. Wearables are making their way into healthcare and everyday life, and we are starting to see the development of new devices beyond smart glasses and smartwatches.

One of the most important factors for creating competitive devices is innovation in materials technology. For wearable devices, especially, it is essential to make electronic parts lighter, thinner, and smaller, which requires significant progress in material science.

In this context, “fine copper powder” has recently gained significant attention. This advanced material supports the evolution of wearable devices by enabling greater flexibility and single-use options, increasing the practicality of wearables.

In this article, we will introduce the potential of fine copper powder, especially our “UCP Series,” for next-generation wearables and semiconductors.

With rapid advancements in IT and electronics, the scope of wearables is expanding beyond traditional watches and glasses to include patches attached to the skin, and even clothing and accessories.

These wearable devices are already being applied in a variety of areas, such as healthcare, sports, nursing care, and safety management.

For example, wearable health monitors can continuously track vital signs, providing real-time information for both users and healthcare professionals. Smart sports gear can measure physical performance and offer personalized feedback.

As wearables become more widespread, there is increasing demand for devices that are lightweight, comfortable, and unobtrusive in everyday life.

Fine copper powder can be used in a variety of wearable applications, such as:

• Flexible sensors and circuits for measuring vital signs in healthcare
• Conductive textiles for smart clothing
• Stretchable electrodes for patches attached to the skin
• Lightweight, single-use diagnostic devices

The ability to print electronic circuits onto flexible materials is opening up new possibilities for design and functionality in wearables.

For wearables to become a seamless part of daily life, devices must be as lightweight and comfortable as possible. There is also a need for flexibility so that devices can conform to the body, and for disposability, which is important for hygiene and convenience—especially in healthcare settings.

This means that not only device design but also the materials used are under the spotlight. Innovation in materials is essential for making wearable devices that are thin, light, and flexible.

Challenges in Making Wearable Devices a Reality

There are still many technical hurdles to overcome before wearables can reach their full potential. These include:

• Miniaturization of electronic components and batteries
• Flexibility and stretchability of circuits and sensors
• Ensuring stable electrical conductivity even when the device is bent or stretched
• Keeping manufacturing costs down

To address these challenges, the development of new materials with excellent electrical properties and processability is essential.

Copper is a metal with excellent electrical conductivity, second only to silver, and is widely used in electronic devices.

Fine copper powder, made by refining copper into microscopic particles, offers several advantages:

• It can be sintered at low temperatures
• It provides high electrical and thermal conductivity, while being less prone to migration than silver
• It enables the creation of thin, lightweight, and flexible circuits.
• It can help reduce production costs compared to silver-based materials.

Because of these properties, fine copper powder is gaining attention as a key material for next-generation wearable devices and printed electronics.
