The role and importance of electrical and magnetic sensors in the wearable device market are expected to expand significantly in the future. They will become key elements that not only improve current functionalities but also open up new possibilities. We can anticipate changes in several aspects:

1. Deepening in Healthcare and Wellness:

• Precise Biosignal Monitoring: Sensors that accurately measure a wider range of biosignals, such as heart rate, electrocardiogram (ECG), electromyogram (EMG), and electroencephalogram (EEG), will be developed. This will enable chronic disease management, early diagnosis, and personalized health management services. For example, linkage with continuous glucose monitoring sensors and drug delivery sensors can revolutionize blood sugar management for diabetic patients.
• Advancement in Sports and Fitness: By analyzing posture during exercise and measuring muscle activity, these sensors will contribute to maximizing exercise effectiveness and reducing the risk of injury. Combined with virtual reality (VR) and augmented reality (AR) technologies, they can also provide more immersive exercise experiences.
• Mental Health Management: Monitoring stress levels, sleep quality, and emotional states can be utilized to provide mental health management services. In addition to biosignals, measurements of electrodermal activity (EDA) will enable more accurate analysis.

2. Innovation in User Interfaces:

• Development of Gesture Recognition and Motion Control: More sophisticated gesture recognition technology will allow for convenient operation of wearable devices. For example, interfaces that allow users to play music or answer calls with simple hand gestures will become possible.
• Implementation of Context-Aware Computing: By comprehensively analyzing sensor data, it will be possible to understand the user’s situation and context and provide tailored services. For instance, intelligent services such as automatically activating navigation functions while driving and activating sleep analysis functions during sleep will be possible.

3. Emergence of New Form Factors:

• Skin-Attachable and Implantable Sensors: Sensors in the form of skin patches or implantable devices will be developed, enabling more continuous and precise biosignal monitoring. For example, patch-type sensors for heart rate monitoring and implantable sensors for glucose measurement may become commercialized.
• Fiber-Type Sensors and Smart Clothing: Sensors embedded in fabrics will allow for natural measurement of biosignals and analysis of movements during daily life. For example, sensors embedded in sportswear can correct exercise posture, and sensors embedded in patient gowns can be used to monitor patient conditions in real-time.

4. Sensor Fusion and Utilization of Artificial Intelligence:

• Advancement of Sensor Fusion Technology: Combining data from various types of sensors will enable obtaining more accurate and reliable information. For example, combining accelerometer, gyroscope, and GPS data can lead to more accurate estimations of travel paths and speeds.
• AI-Based Data Analysis: Analyzing sensor data with artificial intelligence algorithms will enable the extraction of deeper insights and the provision of predictive functions. For example, analyzing heart rate and activity data can predict the risk of heart disease or analyze sleep patterns to suggest ways to improve sleep quality.

5. Development of Energy Efficiency and Miniaturization Technologies:

• Development of Low-Power Sensors: To extend the usage time of wearable devices, sensors with more efficient energy consumption will be developed.
• Development of Ultra-Small Sensors: Smaller and lighter sensors will be developed, increasing the design freedom of wearable devices and improving wearability.

Through these changes, electrical and magnetic sensors will establish themselves as a core competitive advantage of wearable devices and are expected to play a significant role in innovating our health management, daily life, and user experience.
