# Futuristic Wearable Observational Synthetic Dataset

This dataset represents a fully synthetic, multi-decade observational record of 100 individuals monitored by an advanced wearable device.

Measurements include physiological, biochemical, behavioral, environmental, and organ-level digital biomarkers, representing both currently measurable signals and speculative signals that may become measurable in future decades.

All data are generated algorithmically. No real individuals, clinical data, or proprietary sources were used.

---

## Overview

This dataset simulates a long-term population study in which each participant wears a continuous health-monitoring **wearable device**. Measurements are recorded **every 60 minutes**, producing dense, multi-system time-series data.

The wearable’s sensor suite is defined by three technological eras:

- **2025 era:** present-day wearable capabilities  
- **2035 era:** emerging physiological and metabolic biomarkers  
- **2045 era:** advanced multimodal, biochemical, and AI-derived sensing  

In this dataset, all participants use the **2045-era** sensor configuration, enabling the complete set of measurements.

The simulation incorporates:

- Circadian, behavioral, and environmental cycles  
- Physiological variability  
- Polygenic risk modifiers  
- Organ-specific digital biomarkers  
- Rare episodic events (infection onset, arrhythmias, ER visits)
