Soft hydrogel grippers have attracted considerable attention due to their flexible/elastic bodies, stimuli-responsive grasping and releasing capacity, novel applications in specific task fields. To create soft with robust of various types objects, high load capability, fast grab response, long-time service life, researchers delve deeper into materials, fabrication strategies, underlying actuation mechanisms. This article provides a systematic overview materials used grippers, focusing on composition, chemical functional groups, characteristics the strategies for integrating these responsive including one-step polymerization, additive manufacturing, structural modification are reviewed detail. Moreover, ongoing research about actuating mechanisms (e.g., thermal/electrical/magnetic/chemical) is summarized. Some remaining challenges future perspectives also provided. work highlights recent advances which useful insights development new generation grippers.

UV ozone‐modified Fe₃O₄‐PDMS film for solvent‐driven soft actuators with controlled and multi‐stable deformations

Journal of Applied Polymer Science, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 3, 2024

Abstract In recent years, solvent‐driven actuators have been capable of controlling deformations in response to external stimuli. However, a magnetic polydimethylsiloxane (PDMS) composite film with properties is traditionally developed using the micro‐electro‐mechanical system process. Although it has general actuation deformation, suffers from problems and control. Here, this done by co‐mixing PDMS ferrosoferric oxide (Fe 3 O 4 ) then waiting for curing undergoing ultraviolet‐ozone (UVO) surface treatment. By adjusting time orientation UVO treatment, series multiform steady‐state structures (e.g., mono/bistable helix) proposed. addition, deformation under different geometrical parameters constraints was visually predicted incorporating finite element analysis methods. controlled (such as box‐like, folded, so on) are carried out self‐morphing design. Finally, four bionic applications also proposed demonstrate practical use soft based on Fe ‐PDMS films robots. This work provides new strategies designing fabricating programmable controllable lays foundation wide range smart material applications.
