Abstract

For many decades, sensing has been a key global application for many commercial and defence applications [1]. Early sensing technologies has been using either electrical (or RF/Microwave) technologies however, in recent global research and development has focused on smart optical sensing technologies. Predominantly these technologies provide: (a) compact and robust (b) immunity to electromagnetic interference; (c) use of low cost telecommunication fibre cables; (d) long distance; and (e) not susceptible to harsh environment [1, 2] (f) ease of manufacture and other factors. The optical sensing technologies have been applied for leak detection, vibration/perimeter detection and health monitoring due to its high sensitivity and localisation with sub-metre spatial resolution. In traditional optical sensing technologies have been used in monitoring of large-scale perimeter and pipeline monitoring [3] due to the cost of the technology. Due to the compact, robust, high sensitivity, ease of manufacture and accuracy of the detection, these technologies have now been applied in many global Healthcare monitoring with particular interest for the use of biosensors [4-6] and implemented into Bioelectronics or Biotechnology devices and instruments [7-10]. Current and next generation optical sensing technologies are used as biosensors [11]. It has been used in many health monitoring applications such as heartache advance monitoring, wearable technologies in health care monitoring such as Diabetics, Gut monitoring and many other applications. In this talk, a comprehensive review current and future trends of Biosensors and Bioelectronics devices will be presented using optical technologies which are key technologies for healthcare monitoring
