摘要
采用LTCC低温共烧工艺制备了(Pb0.97La0.0 3)(Zr0.75Sn0.25-xTix)O3(x=0.10,0.105,0.11)系列组分反铁电陶瓷厚膜功能材料。实现了对预定温度的灵敏热电换能响应,温度诱导相变电流密度达10-5A·cm-2量级。采用电流/电压转换、自动增益控制和负载增强模块构成的信号处理电路系统,产生面向后级控制应用的TTL脉冲触发信号(4.8±0.2 V),实现基于PLZST厚膜相变电流的温度传感方法与系统,为新型功能材料温度传感控制提供了一种新的技术途径。
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.
