Outline of Final Research Achievements

In this study, the wireless safety monitoring sensor system by a IC sensor-tag applying the wireless communication/sensor and power transmission technology was demonstrated. This system consists of RF-ICs and the IC sensor-tag by a hybrid integrated circuit, a compact base station and firmware to control data sending, sequence, and wireless powering.
We obtained the official experiment license to realize the system and proved the compatibility of sensor information and date sending by the Zigbee operating at 2.45 GHz with microwave power transmission at 5.8 GHz in the reusable spacecraft prototype model. From this study, we are confirmed that the wireless safety monitoring sensor system for the complete harness-free reusable spacecraft is feasible using the wireless information/communication and power transmission technology.
