Special Issue Information

Dear Colleagues,

Micro/nano materials, innovative substances at the micrometer or nanometer scale, are revolutionizing sensor technology with their unique physical and chemical properties. Their high specific surface area and surface activity make them ideal for creating high-sensitivity sensors. These materials are extremely sensitive to environmental changes, capturing even minute fluctuations in temperature, gas concentration, and other physical or chemical parameters.

Surface modification technology further enhances their selective recognition capabilities, enabling the accurate detection of target substances in complex environments. This efficiency and sensitivity make micro/nano materials stand out in fields such as environmental monitoring and industrial safety.

In marine applications, micro/nano sensors provide real-time water quality and ecological data, supporting marine conservation. Their high sensitivity and low cost enable the rapid on-site detection of marine biotoxins, safeguarding food safety and aquaculture.

Looking ahead, micro/nano sensors will continue to evolve, offering higher precision, lower power consumption, and smaller sizes, poised to transform fields such as environmental monitoring, healthcare, and marine resource development.

This paper presents a high-sensitivity temperature and humidity synchronous measurement sensor based on virtual Vernier demodulation, designed to overcome the limitations of traditional sensors in high-sensitivity and synchronous measurements. By combining a dual-cavity parallel structure with the Virtual Vernier effect (VVE), two interferometers were designed, with one using a temperature-sensitive material (polydimethylsiloxane, PDMS) and the other using a humidity-sensitive material (polyvinyl alcohol, PVA) for temperature and humidity measurement, respectively. Based on actual interference spectra, a modulation function was used to generate the virtual reference interferometer spectrum, which was then superimposed with the sensing interferometer’s spectrum to form a virtual Vernier envelope. By monitoring the displacement of the envelope, precise measurements of temperature and humidity changes were achieved. Experimental results showed a temperature sensitivity of 5.61 nm/°C and 7.62 nm/°C, a humidity sensitivity of 0 nm/%RH and −3.07 nm/%RH, and average errors of 0.64% and 1.10% for temperature and humidity, respectively, demonstrating the feasibility of the method. The introduction of the virtual interferometer effectively reduces environmental interference with the measurement results and avoids the material loss and errors associated with traditional reference interferometers. More importantly, the VVE enables dynamic adjustment of the envelope magnification, thereby enhancing the sensor’s flexibility and overcoming the structural limitations of traditional interferometers. This sensor provides efficient and reliable technological support for future environmental monitoring and climate change research. Full article
