Core Insights - The article discusses the emergence of flexible robotics, which aims to utilize soft materials and flexible actuators to replicate human-like tactile sensations, potentially transforming prosthetics, minimally invasive surgical robots, and wearable devices [2] Group 1: Research Development - A study published in Nature introduces ultrasound-driven artificial muscles made from flexible materials filled with microbubbles that bend when exposed to ultrasound, enabling wireless control for various movements [3] - The design utilizes over 10,000 microbubbles, each precisely sized to resonate at different frequencies, allowing for selective oscillation and distributed thrust, resulting in programmable deformation with high compactness (approximately 3000 microbubbles/mm²), lightweight (0.047 mg/mm²), high strength (about 7.6 µN/mm²), and rapid response (grasping in less than 100 milliseconds) [6][7] Group 2: Applications and Implications - The artificial muscles exhibit excellent scalability from micrometer to centimeter scales, flexibility, and multiple degrees of freedom, with potential applications in flexible robotics, wearable technology, haptic technology, and biomedical instruments [9]
