Nursing Implementation

6.0K
Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

System of Memory

7.2K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory01:24

Working Memory

827
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Molecular Shapes

61.4K
Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

Area of Science:

  • Robotics
  • Materials Science
  • Mechanical Engineering

Background:

  • Shape memory alloy (SMA) wire-based soft actuators traditionally suffer from limited performance due to the constrained stroke of SMA wires within polymeric matrices.
  • This constraint intrinsically couples bending angle and force, resulting in suboptimal performance for SMA-based soft grippers compared to other soft actuator technologies.

Purpose of the Study:

  • To present a novel soft actuation method using free-sliding SMA wires as tendons.
  • To overcome the performance limitations of conventional SMA actuators by decoupling matrix and wire lengths.
  • To enable compact packaging of driving SMA wires for enhanced actuator design.

Main Methods:

  • Implementation of free-sliding SMA wires as tendons within a soft actuator matrix.
  • Integration of SMA tendons into a compact module utilizing bearings for easy implementation in soft gripper configurations.
  • Development of soft grippers with three fingers configured antagonistically or triangulary.

Main Results:

  • Achieved significant increases in bending angle (up to 400°) and tip forces (0.89 N) using tendon lengths up to 350 mm.
  • Demonstrated the capability of the developed soft grippers to grip objects weighing up to 1.5 kg.
  • Measured a maximum pulling force of 30 N for the gripper, with easy installation on a robotic arm.

Conclusions:

  • The free-sliding SMA wire tendon approach effectively decouples actuator length and SMA wire length, leading to substantial improvements in bending angle and force.
  • This method allows for compact SMA wire packaging and versatile integration into various soft gripper designs.
  • The developed soft grippers exhibit robust performance, capable of handling a wide range of objects and easily integrating with robotic systems.
