Fundamentals of wearable sensing/small sensor technology and application to application development

Introduction to Wearable Sensing

Wearable sensing technology is revolutionizing the way we interact with technology and monitor our health.
It encompasses devices that are worn on the body and contain sensors to collect and transmit data.
These devices are not only transforming personal health monitoring but are also used in fields like sports, fitness, and even everyday wellness.
This technology is becoming an integral part of our lives, offering a seamless integration of digital functionalities with our daily routines.

The Basics of Wearable Sensors

Wearable sensors are small electronic devices equipped with sensing capabilities to gather data on physiological and environmental parameters.
They can track various metrics like heart rate, body temperature, and physical activity.
These sensors often include accelerometers, gyroscopes, chemical sensors, and more.
Their small size and lightweight nature make them ideal for embedding into wearables like watches, bands, and clothing.

Types of Wearable Sensors

1. **Accelerometers and Gyroscopes:**
These sensors measure movement and orientation.
They are essential for tracking steps, monitoring physical activity, and assessing balance.

2. **Biometric Sensors:**
These sensors measure physiological data such as heart rate, blood pressure, and oxygen saturation.
They are crucial for health monitoring and fitness tracking.

3. **Environmental Sensors:**
These sensors assess external parameters like temperature, humidity, and UV exposure.
They help users understand their environment and adjust their activities accordingly.

Small Sensor Technology

The advances in miniaturization and sensor efficiency have led to the development of small sensor technology.
