Wireless interface of embedded sensors
- The recent development of integrated communication systems opened the so-called Internet of Things era. The capability for wireless communication is especially demanded for small sensors that might be embedded in a human body or a concrete structure. Once embedded, the physiological signals or internal structural conditions can be monitored wirelessly. The challenge is (1) to design and build a small, but reliable antenna that can endure harsh and uncertain conditions of the surrounding medium and (2) to develop a low-power embedded system including sensing and communication blocks. For this purpose, we develop the tool for EM analysis that can reflect the presence of medium and/or propose miniaturized, broadband antennas of which the performance is insensitive to the medium, and embedded circuit systems that sense the data of interest and wirelessly transfer it to an external reader.
