Article Synopsis
- Plant-available nitrogen, mainly as nitrate, is crucial for plant growth but can be harmful in excess, affecting ecosystems and human health.
- A new type of nitrate sensor has been developed, which uses printed potentiometric technology, featuring ion-selective and reference electrodes with polymeric membranes for better sensitivity and selectivity.
- The sensors were tested and showed a strong sensitivity to nitrate across a wide range of concentrations in both solutions and peat soil, although high levels of calcium affected their performance.
Sensor data can be wirelessly transmitted from simple, battery-less tags using Radio Frequency Identification (RFID). RFID sensor tags consist of an antenna, a radio frequency integrated circuit chip (RFIC), and at least one sensor. An ideal tag can communicate over a long distance and be seamlessly integrated onto everyday objects.
