NRC artikel 4TU.Plantenna | ''Eerst de plant tergen en dan luisteren wat ie zegt''
In NRC Wetenschap van zaterdag 15 oktober is een reportage te lezen van journalist Laura Wismans over de sensorenĀ die de onderzoekers van het samenwerkingsprogramma 4TU.Plantenna afgelopen zomer in de tomatenkas van Delphy hebben getest.

Sensors detecting how plants respond to drought
Last summer, researchers from 4TU Plantenna tested several sensors that can measure drought stress in plants in detail. The sensorsā€™ aim is to detect at an early stage when plants are experiencing critical stress, but also to what extent they can recover after a drought period. The ultimate goal is to use the new sensors for a "stress-alert" system, which will help farmers and growers better manage their crops during stress conditions, such as a heat wave or future water scarcity.

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 Verbiestā€™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.Ā

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.Ā

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, Ā 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 helpĀ 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.
