“…However, the applied contact forces on the sensor can be either along the normal direction to the sensor interface, or in the tangential direction. In practice, a device should be able to detect both kinds of forces simultaneously, but this fundamental function has been overlooked by most of the previous studies . Hence, it is necessary to design a TENG‐based tactile sensor that can measure both normal and tangential forces applied on the device, which can further promote the practical applications of TENG technique in the fields of industrial robotics, human–machine interactions, etc.…”

A tactile sensor should be able to detect both normal and tangential forces, which is mandatory for simulating human hands, but this fundamental function has been overlooked by most of the previous studies. Here, based on a triboelectric nanogenerator (TENG) with single-electrode mode, the fully elastic and metal-free tactile sensor that can detect both normal and tangential forces is proposed. With tiny burr arrays on the contact interface to facilitate the elastic deformation, the detected normal pressure by the device can reach to 1.5 MPa with a sensitivity of about 51.43 kPa V −1 , and a large range of tangential forces can be detected ranging from 0.5 to 40 N with rough sensitivity of 0.83 N V −1 (0.5-3 N) and 2.50 N V −1 (3-40 N). Meanwhile, the applied tangential forces from different directions can also be clearly distinguished by the four-partitioned electrode structure. Moreover, a shield film is coated on the top surface of the device, which can screen the electrostatic interference and enhance the repeatability of the device. The demonstrated concept of this self-powered tactile sensor has excellent applicability for industrial robotics, human-machine interactions, artificial intelligence, etc.

Ionic liquids (ILs) have many attractive properties. For example, their physical and chemical properties can be tuned by a judicious design of the cations and anions, making them ideal candidates for designable building blocks of stimuli-responsive materials. Numerous IL-based stimuli-responsive materials have been developed by chemical modification (covalent, coordination, or ionic functionalization) or physical blending of ILs with other functional materials. The flexible tunability of ILs provides a great opportunity to achieve the desired physicochemical properties for taskspecific applications, such as sensing, display, gas capture, and so on. This review aims to address the recent advances in IL-based stimuli-responsive materials, which are categorized by the type of external stimuli, including gas-responsive, organic solvent-responsive, ion-responsive, pH-responsive, thermo-responsive, photo-responsive, and electro-responsive materials.

Irreversible organ damage or even death frequently occurs when humans or animals unconsciously drink contaminated water. Therefore, in many countries drinking water is disinfected to ensure harmful pathogens are removed from drinking water. If upstream water treatment prior to disinfection is not adequate, disinfection by-products (DBPs) can be formed. DBPs can exist as wide variety of compounds, but up till now, only several typical compounds have drinking water standards attributed to them. However, it is apparent that the range of DBPs present in water can comprise of hundreds of compounds, some of which are at high enough concentrations that can be toxic or potentially carcinogenic. Hence, it becomes increasingly significant and urgent to develop an accessible, affordable and durable sensing platform for a broader range and more sensitive detection of DBPs. Compared with well-established laboratory detection techniques, electrochemical sensing has been identified as a promising alternative that will provide rapid, affordable and sensitive DBPs monitoring in remote water sources. Therefore, this article provides a review on current state-of-the-art development (within last decade) in electrochemical sensing to detect organic DBPs in water, which covered three major aspects: (1) recognition mechanism, (2) electrodes with signal amplification, and (3) signal read-out techniques. Moreover, comprehensive quality assessments on electrochemical biosensors, including linear detection range, limit of detection (LoD) and recovery, have also been summarized.
