In the concept of smart environments, miniaturized modules are embedded in everyday objects to provide a better quality of life. Sensors are key elements in these modules. An important issue is how to power the modules for long-term applications. The authors' approach is based on the inductive coupling principle. The 13.56 MHz carrier provides both a power source and a high-data-rate communication medium. Because the powering range achieved is relatively limited (5 to 10 cm), this approach won't provide a global solution, but it's well suited for applications that require high communication capability but contain hard-to-access sensor modules.
