sensor-technology
Sensor technology encompasses devices and systems that detect, measure, and transmit data about physical, chemical, or biological conditions in real time. In plant science, sensors are used to monitor variables such as soil moisture, light intensity, temperature, and leaf gas exchange, enabling researchers to study plant responses to environmental conditions with unprecedented precision. These tools accelerate discoveries in areas like stress physiology, crop optimization, and phenotyping by providing continuous, non-destructive data streams from living plants.

Researchers built a custom microchip that detects cadmium — a toxic heavy metal — at trace concentrations with exceptional sensitivity (273.9 fA noise floor), overcoming the noise and scalability problems that limit conventional electrochemical detection systems.
The system achieves an ultra-low noise level of 273.9 fA (femtoamperes), enabling trace-level cadmium detection
A multi-channel design allows simultaneous detection across multiple samples, improving throughput and scalability
Vertically integrated on-chip electrodes reduce parasitic capacitance that degraded performance in conventional workstations
