Key Role of Chemicals in Enabling the IoT Industry: Materials Powering Innovation and Functionality

The Internet of Things (IoT) is revolutionizing industries and everyday life by connecting a wide range of devices that collect and exchange data. While much of the attention surrounding IoT tends to focus on its software and connectivity aspects, the hardware—particularly the chemicals used in the production of IoT devices—plays a pivotal role in ensuring functionality, efficiency, and durabilit End Quote

(1888PressRelease) January 22, 2025 - With the global IoT device market expected to exceed $70 billion to $80 billion by the end of 2025, the chemicals involved in manufacturing these devices are becoming increasingly significant. By 2025, the value of chemicals directly tied to IoT devices could range from $11 billion to $16 billion (IoT components likely represent a 15% to 20% share of the total cost of an IoT device, though this can vary by device category), underlining the growing importance of materials that power the devices we rely on. The key chemical components in IoT devices include semiconductors, conductive materials, batteries, plastics, polymers, flexible materials, and protective coatings.

The key manufacturers of IOT devices include Samsung Electronics, Huawei, Cisco Systems, Intel, Bosch, Siemens etc.

Here is a closer look at how each of these chemicals contributes to the success of IoT technology:

Semiconductors and Conductive Materials:

Semiconductors play a crucial role in the operation of IoT devices by processing data, enabling sensor functionality, and facilitating seamless data transmission. Typically, these semiconductors are crafted from silicon, a fundamental element that forms the basis of integrated circuits (ICs), transistors, and sensors—key components in almost all IoT devices.

Moreover, conductive materials such as silver, copper, and carbon are essential for building circuit boards, antennas, and sensors. These materials are responsible for ensuring efficient electrical flow, which is vital for IoT devices, especially those that are compact or flexible, where optimizing both space and power consumption is critical.

Batteries and Energy Storage:

Energy storage is essential for IoT devices, especially those that need to operate continuously or remain portable without direct access to a power source. Lithium is the primary chemical used in the energy storage systems of IoT devices, with lithium-ion and lithium-polymer batteries being the most chosen due to their high energy density, lightweight design, and long-lasting performance. These features make them particularly suitable for devices such as wearables, smart sensors, and environmental monitoring devices.

For specific use cases, supercapacitors, which are made from materials like carbon-based compounds and electrolytes, are employed to deliver quick energy bursts and help stabilize power systems. These are particularly valuable in devices requiring fast charging capabilities or a consistent energy supply.

Plastics, Polymers, and Flexible Materials:

The design of IoT devices, which are often small, lightweight, and portable, depends significantly on the use of plastics and polymers. These materials are essential for creating protective casings that shield the sensitive internal components of the devices. Commonly used chemicals in this category include polycarbonate, acrylonitrile butadiene styrene (ABS), and thermoplastic elastomers (TPE). These substances offer a balance of durability, flexibility, and the capacity to be molded into various shapes without affecting the device’s functionality.

Additionally, conductive polymers are gaining importance, especially in the realm of flexible electronics. These materials enable the circuitry of IoT devices to bend and conform, making them suitable for wearable technologies and other devices that need to adapt to different shapes, such as those worn on the human body or integrated into unique environments.

Sensing Materials:

A key feature of many IoT devices is their capacity to detect and monitor various environmental factors, such as temperature, humidity, air quality, and motion. The chemicals used in these sensors are tailored to the specific type of data being collected, with each sensor requiring specialized materials to accurately capture and process the relevant information.

Chemical sensors rely on precise chemical reactions to identify gases such as carbon dioxide or volatile organic compounds (VOCs). These sensors play a vital role in applications like air quality monitoring, where detecting and measuring harmful gases is essential for environmental and health purposes.

Nanoscale materials, including nanoparticles, nanowires, and carbon nanotubes, are being increasingly utilized to improve the sensitivity and performance of sensors. These materials are particularly beneficial in applications like wearable devices and smart sensors, where they help monitor environmental changes or track health-related data with greater accuracy and efficiency.

Protective Coatings and Adhesives:

To enhance the durability and lifespan of IoT devices, protective coatings are applied to safeguard sensitive internal components from environmental factors such as moisture, dust, and extreme temperatures. Silicone-based and epoxy-based coatings are commonly employed due to their ability to provide robust protection while ensuring the device continues to function effectively in challenging conditions. These coatings help extend the device's life by preventing damage to internal parts.

Adhesives also play an essential role in the assembly of IoT devices, especially in compact and complex designs. Polymer-based adhesives are frequently used to bond components, ensuring they remain securely in place without compromising the device's performance or overall functionality.

Price Watch Analysis: The IoT device market is expected to grow from USD 11.7 billion in 2024 to USD 45-50 billion by 2035, reflecting a strong expansion driven by several key factors. The increasing adoption of 5G technology is enhancing connectivity, while rising consumer demand for smart devices and the growth of Industrial IoT (IIoT) are contributing to market acceleration. Additionally, advancements in artificial intelligence (AI) and data analytics are enabling more efficient, intelligent IoT solutions across industries. As IoT manufacturers aim to develop smaller, more powerful, energy-efficient, and flexible devices, innovations in materials for semiconductors, energy storage, and sensors are becoming crucial. These technological advancements are not only shaping the future of IoT but are also driving a significant increase in the demand for specialized chemicals. As IoT applications expand into diverse sectors like healthcare, smart cities, and industrial automation, the need for advanced chemicals in device manufacturing will continue to grow, fueling further market development.
