Topics
BioSense Review covers wearable biosensor technology from the ground up. Below is an overview of the areas we write about.
Sensor Types
- Photoplethysmography (PPG) — heart rate, SpO2, blood pressure estimation
- Electrocardiography (ECG) — single-lead wearable ECG, arrhythmia detection
- Bioimpedance — body composition, hydration, respiratory rate
- Electromyography (EMG) — muscle activity and fatigue
- Electrodermal activity (EDA) — stress and arousal
- Accelerometry and inertial sensors — movement, gait, sleep staging
Health Metrics
- Blood pressure monitoring — continuous and cuffless approaches
- Heart rate variability — measurement methods and clinical meaning
- Blood oxygen saturation — accuracy factors and real-world limitations
- Atrial fibrillation detection — how wearable screening actually works
- Sleep staging — what algorithms can and cannot determine
- Stress and recovery indices — what the scores are based on
- Non-invasive glucose monitoring — current state of the technology
Regulation and Validation
- FDA clearance vs. approval — what each means for a health wearable
- 510(k), De Novo, and PMA pathways explained
- Blood pressure validation standards — ISO 81060-2 and AAMI SP-10
- How to read a clinical validation study
Device Reviews
Technical reviews of consumer and clinical-grade wearables. Every review covers sensor design, signal processing approach, regulatory status, and available validation evidence.
Explainers
Plain-language explanations of the science behind health wearables. Written for readers who want to understand the technology, not just the marketing.
