From researcher to tomato picker | Plantenna Blog #10
With the start of the Plantenna research program, several sensing-based projects emerged. One of these was the development of a new ultrasound sensor for detecting plant stress inside the plant. Satadal Dutta and Gerard Verbiest’s promising results using this sensing method culminated in a paper and a patent. Now, Berend and Thijs have the task to bring this technology to market with their start-up Plense Technologies.

Using plants as antennae | Plantenna Blog #9
Using a plant to increase the radiation efficiency of an antenna, it seemed like science fiction until recently. However, a simulation study including an Antenna Booster, a simple printed circuit board (PCB) and a basic leaf model showed that the use of the plant itself as an antenna might actually be closer to reality than we think.

Flow in the dark | Plantenna Blog #8
Frost that destroys the flowers buds of fruit trees is a recurring problem with severe damage to fruit production. In order to better understand when and where the flower buds are at risk and how to mitigate the damage, the Fruit frost project was started (Clarity on Fruitfrost (4tu.nl)).

Looking inside the plant with MRI scanners | Plantenna Blog #7
How can we visualize a plant from within to diagnose the plant's health without cutting into its tissue? The solution can be found in ultra-high field MRI scanners; two to nine times stronger than hospital MRI scanners.

Thousands of autonomous plant sensors| Plantenna Blog#5
In the last decade we have witnessed exponential growth in wireless communications. Number of connected devices exceed the number of people on earth and the data rates can be as high as 1GB/s. The next wave in wireless technology will be about sensing the environment.

Which frequency to tune to? | Plantenna Blog #4
Despite the availability of various monitoring mechanisms such as measuring temperature, water content, soil nutrients, very little is leveraged for sensing applications in the agriculture and horticultural sectors.

Plants as organic river cleaners | Plantenna Blog #3
As hydrologists we are interested in the interaction between plans and the water cycle. We traditionally look at plant transpiration, the interception of precipitation by leaves, or detection vegetation water stress. However, new global environmental challenges also come with new roles for plants.

FruitFrost project Plantenna in BNR Podcast
Professor Bas van de Wiel, researcher at the 4TU Plantenna programme, tells BNR news radio about the FruitFrost project in which sensors measure the temperature of plants and small windmills keep the soil frost-free. A great help for growers and farmers who now have to get out of bed to save the plants. In the near future, sensors will automatically indicate whether help is needed and turn it on themselves.

International Micro Nano Conference Utrecht 2019
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.

IEEE MetroAgriFor workshop 2019
D. Cynthia Maan from TU Delft presented at the IEEE International Workshop on Metrology for Agriculture and Forestry in October 2019, where she and her co-authors studied the coupled action of water uptake and root development of maize in potting soil under greenhouse conditions. Synchronous realtime measurements of the co-evolving soil moisture fields and root distributions were performed. Understanding of the feedback loops between the soil moisture distribution and root development opens new pathways for boosting natural adaptation and climate resilience of plants.
