Continuous plant phenotyping needs sensors that are not only soft and light but also transparent enough to avoid blocking photosynthetic light. A 2024 Science Advances study developed an all-organic PEDOT:PSS/PDMS plant e-skin.
4.5 µm thick and over 85% transparent
Micropatterned PEDOT:PSS was embedded in stretchable PDMS. The complete e-skin was only 4.5 µm thick and transmitted more than 85% of visible light from 400–700 nm. PEDOT:PSS features as small as 2 µm were demonstrated.
Strain and surface-temperature sensing
Attached to juvenile Brassica rapa leaves, strain sensors captured leaf growth and day/night growth rhythms, including changes under abiotic stress. Thermoresistive sensors tracked leaf-surface temperature.
Low observable impact is not proof of zero impact in every crop
The authors observed no clear adverse plant-health effect and argue that transparency, thinness, gas permeability and placement on the adaxial surface minimize interference. The work did not establish unchanged long-term photosynthesis or yield for every crop species.
A digital twin, not virtual-reality farming
Sensor data were mapped onto a virtual digital-twin plant for intuitive visualization of leaf-surface conditions. The interface is a data-visualization layer rather than a full VR cultivation system.
