dr. S. Dutta from TU Delft presented his talk at the iMNC held in Utrecht on 10 December 2019, where he discussed about the applications of low-cost optoelectronics for continuous and non-invasive near infrared reflectance sensing on leaves, which can reveal the structural information of the leaf mesophyll tissue and its dynamic response to water-stress. With his personal research interest in silicon optoelectronics, he calls for large-scale integration of these sensors in CMOS with silicon LED and silicon photodetector that can operate near 1100 nm wavelength.
