wearable-biosensors
Wearable biosensors are miniaturized, flexible electronic devices that can be attached directly to plant surfaces to continuously monitor physiological and biochemical signals in real time. In plant science, these sensors enable non-destructive, in-field measurement of key indicators such as leaf water potential, ion fluxes, volatile emissions, and growth-related mechanical changes. This technology accelerates research into plant stress responses, nutrient dynamics, and environmental adaptation by providing high-resolution, continuous data that traditional sampling methods cannot achieve.

Scientists built a wearable sensor patch that can be attached to living plants to detect salt stress early — without harming the plant — by simultaneously tracking potassium ions and stress hormones in real time.
The wearable sensor enabled noninvasive, in situ monitoring of potassium (K⁺) ion dynamics and hormonal signals simultaneously, without destructive sampling
The system detected salt stress responses earlier than conventional single-parameter methods by capturing crosstalk between ionic and hormonal signaling networks
Soil salinization disrupts plant ion homeostasis and triggers complex hormonal cascades that the device can track in real time, revealing stress progression dynamics previously obscured
