Silicon Device-Based Sensing for Sustainability

Sustainable agriculture can address two interlinked global challenges of climate change and food security. However, sustainable agricultural practices are limited by the lack of inground chemical sensors for soil [1]. This limitation occurs because reference electrodes (RE) of electronic sensors fail when inserted in soil. To overcome this limitation, an innovative RE has been proposed, validated, and extensively evaluated in soil. It is also integrated into a manufacturable silicon device-based sensing portable prototype, thus advancing inground sensor technology for sustainability.
