| Abstract: | Anti-ferroelectric （ Pbo. 97 Lao. 03 ） （ Zr0.75 Sn0.25-xTix ） 03 （ x = 0. 10,0. 105,0. 11 ） ceramic thick film functional materials with series of components were fabricated through LTCC （Low Temperature Co-fired Ceramic） technology. The sensitive response with thermoelectric transducer to the specific temperatures was achieved. The current density released from phase transition was up to 2.5×10-6A · cm^-2. The TTL pulse trigger signal（4.8±0.2V） aimed to the after control application was generated by the signal processing circuit system integrated with current/vohage converter,automatic gain control and load enhancement modules. The temperature sensing method and system based on phase transition current of PLZST thick films was implemented. A technical approach was provided for temperature sensing control method with novel functional materials. |
