Wireless sensors are expected to be low cost and to reduce their power consumption so that a large number of sensors can be installed for collecting real-world information. Passive radio-frequency identification (RFID) is proposed to assign communication channels to sensors that only send analog sensing signals for their multiple access control. In this method, the RFID reader-writer assigns channels...
Synthesis of non-doped and Y-doped SrTiO 3 polycrystals was tried by the polymerized complex (PC) process and the subsequent hot pressing at 1473K and 1673K. The effects of hot pressing temperature on thermoelectric properties of these SrTiO 3 sintered bulks were investigated. The PC process could provide the powder precursor with perovskite SrTiO 3 structure even when Y was...
