With the advancement of the Internet of Things (IoT) and wearable electronics, the demand for flexible and highly sensitive thin-film temperature sensors has been increasing. Conventional rigid sensors face limitations in environments requiring conformability and stretchability, leading to active research on thin-film temperature sensors using various materials and fabrication techniques. Metals, metal oxides, polymers, carbon-based materials, and 2D materials have been explored as key candidates for enhancing thermal sensitivity, mechanical flexibility, and long-term stability. Additionally, fabrication approaches such as laser patterning, inkjet printing, and sputtering have improved precision and scalability in sensor production. However, challenges remain in ensuring long-term durability, environmental stability, and seamless integration with emerging technologies. This review highlights recent advancements in thin-film temperature sensors, focusing on external strategies for performance enhancement and practical applications. Furthermore, it discusses key technological challenges and future research directions essential for the continued development of thin-film temperature sensors.

The processes of thermoforming 2D-printed electronics into 3D structures can introduce defects that impact the electrical performance of conductors, making them more susceptible to thermal failure during high electrical power/current applications on temperature-sensitive substrates. We therefore report the use of a thin-film boron nitride nanotube (BNNT) interlayer to directly reduce heat stress on linear and serpentine metallic traces on polycarbonate substrates thermoformed to 3D spherocylindrical geometries at varying elongation percentages. We demonstrate that the BNNT interlayer helps to improve the electrical conductivity of highly elongated thermoformed 3D traces in comparison to traces on bare polycarbonate.

MoSe nanosheet/Si heterojunction photodetectors were fabricated by a mechanical exfoliation method, and their electrical and optical properties at different temperatures were investigated. It was found that the MoSe nanosheet/Si heterojunction device exhibited excellent rectification characteristics at room temperature, and the rectification ratio gradually decreased with the decrease of temperature. The temperature-dependent electrical properties of the MoSe/Si heterojunction device were actually caused by the inhomogeneity of the potential barrier.

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.

Altermagnets are a newly identified family of collinear antiferromagnets with a momentum-dependent spin-split band structure of non-relativistic origin, derived from spin-group symmetry-protected crystal structures. Among candidate altermagnets, CrSb is attractive for potential applications because of a large spin-splitting near the Fermi level and a high Néel transition temperature of around 700 K. Molecular beam epitaxy is used to synthesize CrSb (0001) thin films with thicknesses ranging from 10 to 100 nm.
