Micro-sensors under the skin provide real-time health data The US biotech company Proteus Digital Health has developed a system of injectable micro-sensors that are implanted in the body and continuously collect health-relevant data. The system aims to personalize medical care and make chronic diseases more manageable. How does it work?Micro-sensors are injected into the skin or under the muscle.They measure parameters such as: Blood glucose levels Body temperature Inflammatory markers Heart rate and blood pressure The data is transmitted via Bluetooth or NFC to an app or a medical dashboard. Applications: Diabetes management Postoperative monitoring Prevention of strokes and heart attacks Medication adherence tracking Privacy & Ethics: Data is end-to-end encrypted. Patients retain full control over access and sharing. Discussions on the limits of body monitoring and medical privacy are increasing. Significance: Enables more precise and proactive medicine. Could reduce hospital stays and lower treatment costs in the long term. Part of the movement toward “Digital Health 2.0” – medical care based on real-time data.
