Metamaterial sensors apply metamaterials rather than metals to improve the sensor selectivity, sensitivity, enhanced focusing.

can exhibit a strong localization and enhancement of fields so that they can be used to actually improve the sensor selectivity of detecting nonlinear substances and to enable detection of extremely small amounts of analytes

Metamaterials are artificial media structured on a size scale smaller than wavelength of external stimuli, and they can exhibit a strong localization and enhancement of fields, which may provide novel tools to significantly enhance the sensitivity and resolution of sensors, and open new degrees of freedom in sensing design aspect. Metamaterials-based sensing, and detailed priniciple reviews, detecting process and sensitivity of three distinct types of sensors based on metamaterials, as well as their challenges and prospects. Moreover, the design guidelines for each sensor and its performance are compared and summarized.

Strain sensors
"Since artificial materials with unusual properties, such as negative refractive index, have been introduced to manipulate beams of light in different ways, the broad potential applications of metamaterials have emerged.
