Nanoscience and Microsystems ETDs
Within this research, I have developed a microneedle-based wearable sensor for plants and fungi, to measure the electrical impedance of different tissues. Electrical impedance measures the physical properties of a material while allowing complex biological systems to be modeled onto a simplified electrical circuit. Microneedles allow for electrical impedance to measure specific tissues without the insulative properties of the cuticle and can be applied to delicate tissues. I have demonstrated the tissue specificity, novel attachment methods, as well as use on both plants and fungi. In chapter 1, I applied microneedle-based impedance to the leaf midrib of a sorghum and …
