Abstract

Monitoring of one or more key indicators can provide powerful insights into operation and state of different physical systems. For example, continuous monitoring of multiple analyte in body will allow for detailed insights into personal health and will allow for preventative health management. In this application, we present an ultra-small scale wireless sensing platform capable of long-term wireless in-vivo sensing. The key for extreme miniaturization lies in ultra-low-power compact design and lithographic integration of key system components. The key to low cost is using standard technologies and scalable manufacturing. For example, using standard semiconductor technologies for sensing, processing and wireless operation paves way to a low-cost integrated wireless sensing technology. Modern semiconductor technologies provide the capability to provide low-power and yet powerful electronics functionality in a small (mm-scale) size and wireless operation at high frequency. Furthermore, these technologies also present the possibility of integrating different components through wafer-scale lithographic integration. This application presents optimal design and processing methods for a small wireless multi-analyte sensing platform that can be used to monitor multiple analyte such as glucose, lactate, Urea and other physicochemical quantities and operates wirelessly. The design techniques and processing methods presented in this application can be used for a multitude of other applications and are not limited to those described here.
