Scientists develop new battery-free lactic acid sensor
Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source.
Functional materials are physical systems engineered so that their intrinsic properties—such as electrical conductivity, magnetization, optical response, ionic mobility, or mechanical deformation—can be deliberately modulated by external stimuli (e.g., electric or magnetic fields, light, temperature, stress, or chemical environment) to perform specific tasks. They encompass classes such as ferroelectrics, piezoelectrics, magnetoresistive and thermoelectric materials, shape-memory alloys, solid electrolytes, and stimuli-responsive polymers. In research and device design, functional materials serve as active components enabling sensing, actuation, energy conversion, information storage, and signal processing, with performance governed by their structure–property relationships across atomic, mesoscale, and macroscopic length scales.
