This review article provides an overview of recent advances in tactile sensory systems, focusing on mechanisms, fabrication techniques, and applications. Tactile sensors, which mimic biological functions of sensing mechanical stimuli, have significant potential in enhancing human-machine interactions (HMIs). However, they face challenges in achieving high sensitivity, environmental adaptability, and effective data interpretation. The article discusses various types of tactile sensors, including piezoresistive, capacitive, piezoelectric, and triboelectric sensors, highlighting their unique characteristics and applications. It also reviews state-of-the-art fabrication techniques such as inkjet printing, 3D printing, 4D printing, and transfer printing, which are crucial for improving the performance and compatibility of these sensors. The applications of tactile sensors in intelligent robotics, wearable devices, prosthetics, and medical healthcare are explored, emphasizing their role in improving dexterity, precision, and sensory feedback. Finally, the article concludes with a discussion on the current challenges and future trends in the development of tactile sensors.This review article provides an overview of recent advances in tactile sensory systems, focusing on mechanisms, fabrication techniques, and applications.
