Advancements in Flexible Tactile Sensors for Robotic Dexterous Grasping

This paper examines the application of flexible tactile sensors in robotic dexterous grasping, focusing on improving grasping accuracy and stability through distributed tactile sensing and slip detection. The study synthesizes findings from multiple research efforts, highlighting the use of flexible materials like conductive rubber, piezoelectric elements, and capacitive sensors. These technologies enable three-axis force detection and slip prevention during complex grasping tasks by providing real-time feedback on applied pressure and surface interactions. Techniques such as Discrete Wavelet Transform (DWT) further enhance slip detection accuracy. Experimental results show that flexible tactile sensors are highly effective in preventing slippage and adjusting grip strength in real time, particularly for fragile or irregularly shaped objects. This research contributes to the development of more intelligent and adaptable robotic systems, offering valuable insights into future sensor design and implementation. The sensors reviewed offer practical solutions for enhancing robotic dexterity, making them invaluable for industrial and service robots that require fine manipulation capabilities. Potential applications range from precision manufacturing to advanced healthcare robotics.
