COMPOSITIONS, APPARATUS AND METHODS FOR CAPACITIVE TEMPERATURE SENSING |
| 摘要 |
A passive temperature-sensing apparatus, which includes a capacitive sensing element that includes a capacitive sensing composition that includes a ferroelectric ceramic material that exhibits a measurable electrical Curie temperature that is below 30 degrees C. The capacitive sensing composition exhibits a negative slope of capacitance versus temperature over the temperature range of from 30 degrees C. to 150 degrees C. |
