Developments of Organic Sensors and Electronics in Medicine and for Point-of-Care Patient Health Monitoring in Real Time
Keywords: plastic electronics, point-of=care diagnostics, medicine
A new paradigm in healthcare, driven by cost and quality issues, is now emerging, which enables continuous point-of-care (POC) monitoring of patient’s vital signs such as heart rate (ECG), respiration, body temperature, skin response (GSR), and motion activities (EMG). Real-time health monitoring could ensure the effectiveness of therapy by providing prevention, and early risk detection, which will significantly reduce healthcare costs by avoiding unnecessary hospitalizations. The key to POC monitoring is the development of cost-effective, light-weight and low-power consumable sensor devices that can be seamlessly embedded into a daily outfit. Latest advances in organic electronics have the ability to realize light and cost-effective smart fabrics with embedded electronics and sensors combined with wireless communications. In this presentation, we introduce several organic based sensor devices capable of measuring temperature, strain, ph and potassium ion concentrations, each of which will enable us to monitor the patient’s respiration rate, skin/body temperature, and the onset of Acute Myocardial Ischemia. It is expected that these flexible organic sensors can easily fit on garment with wireless instrument, and this sensory suit will be ideal for the real-time monitoring of vital kinematics and signs at remote locations for activity and location monitoring. Selected movies illustrating the applications of both invasive and non-invasive wireless sensor systems to patients and surgical procedures will be shown at the talk.
