And just like humans, environmental conditions can cause plants considerable stress and disease, so preventative care is essential. As reported in ACS Sensors, researchers created a wearable patch ...

Plant Water Sensor. One of the standout features of SmartyPlants is its ability to provide expert insights for plant care. The device analyzes environmental factors such as soil moisture, ...

The increasing global demand for plant-based foods makes the use of pesticides necessary in order to protect crops from pests and ensure crop yields. However, there is one major disadvantage: the ...

"The sensor can be used in different ways," Dong tells us. "One approach involves the farmer applying the sensor to a plant leaf for a one-time, on-the-spot reading across multiple plants.

By measuring how long a particular type of plant’s leaves stay wet, farmers, gardeners, and researchers can improve disease forecasting, making better decisions about management strategy. Commercial ...

Plant sensors could act as an early warning system for farmers Date: April 17, 2024 Source: Massachusetts Institute of Technology Summary: Using a pair of sensors made from carbon nanotubes ...

We created the first plant nano-sensor that detects SA, a key stress hormone, directly within living plants. By combining our SA sensor with an H 2 O 2 sensor, we observed unique patterns of these ...

The electrochemical sensor attaches tiny spikes to plant leaves and monitors hydrogen peroxide, the stress response that triggers the discoloration and wilting of leaves.

SA is a crucial plant hormone for growth, development, and stress response to pathogens, temperature, drought, salinity, metals, UV light, and osmotic stress. The researchers also pioneered a method ...
