Self-Cognizant Bionic Liquid Sensor for Pathogen Diagnosis

Abstract

As observed in the outbreaks of SARS and swine flu, as well as many other infectious diseases, the huge volume of human traffic across numerous enclosed public venues has posed immense challenges to preventing the spread of communicable diseases. There is an urgent need for effective disease surveillance management in public areas under pandemic outbreaks. The physicochemical properties associated with ionic liquids make them particularly suited for molecular communications in sensing networks where low throughput is quite adequate for pathogen detection. This paper presents a self-cognizant system for rapid diagnosis of infectious disease using a bionic sensor such that testing can be supported without collecting a fluid sample from a subject through any invasive methods. The system is implemented for testing the performance of the proposed bionic liquid sensing network.

Recent Advancements of MXene/Nanocellulose‐Based Hydrogel and Aerogel: A Review

“…Generally, adjustable pressure or strain sensors are attached or implanted to the human or robot skin of fingers, mouth, and palms through wearable devices and convert the pressure or force into electrical signals. [216,217] With the rapid expansion of flexible human-computer interfaces and telecommunications, developing a high-sensitivity strain sensor is crucial for detecting human movement. [175] Recently, the unique and specific structures and incorporation of aerogel or hydrogel with composite materials like MXene and nanocellulose strain sensors added an extra dimension in ensuring high sensitivity, [218] fast response, [175] fast recovery times [219,220] and stretchability, [78,[221][222][223] high comprehensive response range, [212,224,225] and high stability performance (see Table 4).…”

3D Porous MXene Aerogel through Gas Foaming for Multifunctional Pressure Sensor

“…Flexible pressure sensors can be attached to the skin of robot fingers, palms, or implanted in wearable devices. By converting forces on sensitive components into electrical signals, the perception of external forces and the detection of microelectronics can be realized [13][14][15]. However, the properties of flexible pressure sensors in practical applications, such as sensitivity, linear detection range, and stability, are often limited by the poor performance of tradi-tional materials [16][17][18].…”
