Summary: Research on aqueous solution sensors is highly demanded for biological sensing applications. This study introduces an approach to enhance the affinity of organic field-effect transistors (OFETs) to aqueous solutions by incorporating amphiphilic molecules in the hydrophobic semiconductor. The modified OFET demonstrates the ability to detect glucose solutions in the human blood range and achieve selective detection of various aqueous solutions. The sensing performance can be tuned by adjusting the composition of the amphiphilic molecules and introducing dielectric materials.

Summary: In the past several decades, high-performance field effect transistors (FETs) have made great progress and become an important component in the field of electronics. They have also attracted attention as tactile sensors for flexible wearable devices, artificial intelligence, and the Internet of Things. FETs have a unique three-terminal structure, enabling them to detect external mechanics through different sensing mechanisms. This review classifies and summarizes structure-optimized FET tactile sensors and discusses their working principles and state-of-the-art protocols. The innovative pixel distribution and integration analysis of transistor sensor matrix arrays for flexible electronics are also introduced.

Summary: The trapping of environmental charges in surface states can dominate electrical transport in nanostructured field-effect transistors used as sensors, leading to exceptional sensitivity. However, the time dependencies on experimental timescales can result in hysteresis of FET conductance and signal instability. While hysteresis is usually suppressed by chemical surface treatments, it can also be studied as a source of information for ion sensing.

Summary: A pH sensor based on EGFET with microfluidic channels and a temperature sensor has been developed to overcome the challenges in body fluid collection and temperature compensation. The sensor, prepared by a low-cost solution-based process, can measure both body temperature and pH of body fluid. It has a temperature coefficient of resistance (TCR) up to 5.17% and shows a difference of only 0.17 celcius from the gold standard in body temperature measurement. The pH sensitivity is 58.41 mV pH(-1), with a deviation of only 0.066 from the standard pH value. The sensor is expected to have large-scale applications in wearable health monitoring.
