Toolkit/passive microwave antenna backscatter readout
passive microwave antenna backscatter readout
Also known as: backscatter communication, passive microwave antenna
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
the response of Escherichia coli is harnessed to trigger the controlled degradation of a passive microwave antenna, which is then monitored via backscatter communication

Published Workflows
Objective: Create a wireless implantable sensing system that couples genetically engineered bacterial molecular detection to externally readable electromagnetic signals for continuous monitoring in tissue-like conditions.
Why it works: The abstract states that EM waves at cellular-scale wavelengths are strongly attenuated in tissue, whereas centimeter-scale wavelengths are needed for in-body links. The system therefore aligns cellular responses with longer-wavelength EM readout by coupling bacterial activity to a passive microwave antenna monitored through backscatter.
