Pervasive sensing with Body Sensor Networks (BSNs) is the new generation of diagnostic tools transforming the traditional episodic patient management to personalised and continuous monitoring of patients' health and wellbeing under their natural conditions. Integrated with miniaturised low cost sensors, a BSN system can provide the needed monitoring of patients' health and wellbeing and alert caregivers when an incident is detected. The system will improve the quality of care, ensure the safety of patients, reduce the workload and reliance on caregivers, and prevent adverse incidents which also means less medical care cost incurred to their family or the government. The system can be used to support further development of automatic health assessment models which will be an essential part of the future predictive, preventive and personalised medicine. We have developed a range of wearable sensing technologies for healthcaree applications, such as:

• A wearable fall prevention device
• A tissue oxigenation sensor
