Flexible microfluidic triboelectric sensor for gesture recognition and information encoding

Synergizing Machine Learning Algorithm with Triboelectric Nanogenerators for Advanced Self-Powered Sensing Systems

“…To enhance the stability of triboelectric electric sensors, quantifying sensor performance through the number of wave peaks rather than the output amplitude has been recognized as an effective method. Ge et al developed a flexible microfluidic triboelectric electric sensor (FMTS) that utilized the flow of liquid in microfluidic channels to generate output signals [ 162 ]. The structure and mechanism of the FMTS are shown in Figure 8 d(i,ii).…”

Wearable and Cost-Effective Pressure Sensor Based on a Carbon Nanotube/Polyurethane Sponge for Motion Detection and Gesture Recognition

“…Flexible sensors have received widespread attention from researchers due to their excellent characteristics such as being lightweight, compressible, and wearable. These sensors have been widely used in various fields, including human motion detection, − health monitoring, − handwriting typing, − and human–machine interaction. − Flexible sensors can be broadly classified into different sensing mechanisms, namely, piezoresistive, − capacitive, − piezoelectric, − and triboelectric. − Among them, piezoresistive sensors have been recognized as the ideal choice for next-generation wearable devices, human–machine interaction, and health monitoring due to their advantages of a simple structure, fast response, and convenient signal acquisition. To obtain both greater sensitivity and a wider detection range, many studies have proposed improvements to piezoresistive sensors.…”

Flexible Sensor for Real-Time Monitoring of Motion Artifacts in Magnetic Resonance Imaging

“…However, as metal electrodes can introduce extra artifacts into MRI images, nonmetallic electrodes are preferred and magnetic metal electrodes cannot be used in the array structure . In previous studies in the TENG field, many different electrode materials have emerged, − and the diversity of these materials ensures that there are materials to choose from when used in MRI scenarios. , …”

“…22 In previous studies in the TENG field, many different electrode materials have emerged, 23−25 and the diversity of these materials ensures that there are materials to choose from when used in MRI scenarios. 26,27 In light of this context, we developed a two-layer graphite electrode sensor based on the head magnetic resonance imaging scanning application scenario. This sensor measures the amplitude of patient movement and records alterations in the electrical signal when the patient moves.…”
