Wearables are electronic devices designed to be worn on the body, providing functionalities that range from health monitoring and fitness tracking to communication and entertainment. This entry explores the history, types, key events, technological aspects, and future implications of wearables.
Historical Context
The concept of wearable technology dates back several decades. Early forms included basic calculators integrated into wristwatches during the 1970s. However, it wasn’t until the 21st century, with the advent of advanced microprocessors, sensors, and wireless communication, that wearables evolved into sophisticated devices.
Types/Categories of Wearables
- Smartwatches: Devices like the Apple Watch and Samsung Galaxy Watch offer functionalities such as notifications, health monitoring, and mobile payments.
- Fitness Trackers: Devices such as Fitbit and Garmin focus on tracking physical activity, heart rate, sleep patterns, and other health metrics.
- Smart Glasses: Google Glass and Microsoft HoloLens provide augmented reality (AR) experiences and hands-free access to information.
- Wearable Medical Devices: These include glucose monitors for diabetes, wearable ECG monitors, and other devices that track vital health parameters.
- Wearable Cameras: Devices like GoPro are used for capturing video in various settings, providing a first-person perspective.
Key Events
- 1975: Introduction of the Pulsar calculator wristwatch.
- 2000s: Development of Bluetooth headsets as wearable communication devices.
- 2013: Launch of Google Glass, one of the first widely known smart glasses.
- 2015: Apple releases the Apple Watch, significantly increasing the popularity of smartwatches.
- 2020: Wearables with integrated health-monitoring features become crucial during the COVID-19 pandemic.
Detailed Explanations
Technological Components
- Sensors: Accelerometers, gyroscopes, heart rate monitors, GPS, etc.
- Microprocessors: Ensure real-time data processing and efficient power management.
- Connectivity: Bluetooth, Wi-Fi, and LTE enable communication with other devices and networks.
- Power: Battery technology advancements ensure longer device life on a single charge.

Mathematical Models
Wearables often use complex algorithms and models to interpret the data they collect:
-
Pedometer Algorithm: Uses accelerometer data to count steps:
$$ \text{Step Count} = \sum_{i=1}^{n} f(A_i, g) $$where \( A_i \) is accelerometer data and \( g \) represents gravitational force. -
Heart Rate Monitoring: Utilizes photoplethysmography (PPG) signals processed through filtering and peak detection algorithms.
