The transition from rigid robotics to soft robotics represents a significant shift in the field, driven by the need for more patient-friendly solutions. Key milestones in this evolution include:

• Development of the first surgical robots in the 1980s.
• Introduction of robotic-assisted surgeries in the 1990s.
• Emergence of soft robotic devices in the early 2000s, focusing on patient interaction.

III. Mechanisms of Soft Robotics

Soft robotics utilizes a variety of materials and design principles that distinguish it from traditional robotic systems. The primary materials used in soft robotics include:

• Hydrogels: Water-absorbent polymers that can change shape and stiffness in response to environmental stimuli.
• Elastomers: Flexible materials that provide the necessary compliance and resilience for soft robots.

The design principles of soft robots often involve biomimetic strategies, where robotic systems are inspired by the natural movements and structures of living organisms. Actuation methods can vary, with common techniques including pneumatic actuators, shape-memory alloys, and electroactive polymers.

When compared to traditional robotic systems, soft robots offer several advantages, including:

• Increased safety due to their compliant nature.
• Better adaptability to complex and dynamic environments.
• Greater ease of integration into patient care scenarios.

IV. Applications of Soft Robotics in Patient Care

Soft robotics has a wide range of applications in patient care, significantly enhancing treatment outcomes and patient experiences. Key areas of application include:

• Rehabilitation and physical therapy devices: Soft robotic exoskeletons can assist patients in regaining mobility and strength after injuries or surgeries.
• Surgical assistance and minimally invasive procedures: Soft robots can navigate delicate areas with precision, reducing patient trauma and recovery time.
• Patient monitoring and support systems: Wearable soft robotics can provide real-time health monitoring while ensuring comfort and safety for the patient.

V. Case Studies: Soft Robotics in Action

Numerous success stories highlight the positive impact of soft robotics in hospitals and clinics:

• A soft robotic glove developed for stroke rehabilitation has shown significant improvements in patient mobility and strength during clinical trials.
