The Internet of Things (IoT) has transformed the way we interact with the world around us. From smart home appliances to wearable fitness trackers, these devices are becoming a part of our day-to-day lives. According to the McKinsey Global Institute, IoT applications will generate between $4 trillion to $11 trillion economy by 2025. However, the foundational element of these advanced devices is semiconductors. Current projections suggest this momentum will push the global semiconductor market toward an aspirational $1 trillion valuation by 2030, largely fueled by the explosion of connected endpoints.
Semiconductors are the building blocks of modern electronics. They are tiny chips made up of silicon that control the flow of electricity and handle complicated computation operations. Due to their versatility, they are used in a wide range of functions, and the development and operations of IoT devices are one of them. Top semiconductor company NXP is working towards developing innovative chip solutions for IOT devices for consumer, automotive, and industrial applications. Modern IoT ecosystems now rely on Heterogeneous Integration, where diverse components like sensors, radios, and processors are combined into a single System-on-Chip (SoC) or System-in-Package (SiP).
The Role of Semiconductors In IoT Devices
Semiconductors play a crucial role in enabling the functionalities of IOT devices. Let’s look closer at their specific contribution to those devices-
Sensing and data acquisition
Semiconductor-based sensors are essential components in IOT applications for data collection. They can promptly detect various environmental parameters like temperature, light, motion, and pressure. They detect and then convert these data or physical quantities into electrical signals.
- Precision Analog Front-Ends (AFEs): Modern sensors use AFEs to clean, amplify, and digitize signals with extreme accuracy before they even reach the main processor.
- MEMS Technology: Micro-Electro-Mechanical Systems (MEMS) allow for the miniaturization of high-performance motion and pressure sensors used in wearables.
Processing and control
The brain of IOT devices are microcontrollers and microprocessors which are powered by semiconductor technology. The semiconductor chips interpret the data received from the sensors, execute programmed instructions, and then make real-time decisions. Actuators are devices that convert electrical signals back into physical quantities or actions that proceed with tasks like adjusting room temperature based on sensor data, or trigger alarms when anomalies are detected. The functionality of the processor unit in IOT devices depends on the specific requirements of the respective device. Devices with simple sensing activities might utilize low-power microcontrollers, while complex IOT devices leverage the advanced processing capabilities of microprocessors.
Connectivity and communication
Semiconductors with their advanced functionality facilitate communication between IOT devices and other systems of the network. Wireless communication modules such as Wi-Fi, Bluetooth, and cellular radio chips are all built using semiconductors. These modules enable data transmission between devices and gateways or cloud platforms that validate remote monitoring, control, and data analysis.
Security and privacy
Security is the most concerning aspect in the interconnected world of IoT. Thus semiconductor companies are moving forward to incorporate security measures in semiconductors. They are developing chips with built-in security features such as encryption engines and secure boot capabilities. These features are developed to safeguard sensitive data collected by IOT devices as well as prevent the situations of potential security risks.
