    • Buckling of Elastomeric Beams Enables Actuation of Soft Machines 

      Yang, Dian; Mosadegh, Bobak; Ainla, Alar; Lee, Ben Charles Germain; Khashai, Fatemeh; Suo, Zhigang; Bertoldi, Katia; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      Soft, pneumatic actuators that buckle when interior pressure is less than exterior provide a new mechanism of actuation. Upon application of negative pneumatic pressure, elastic beam elements in these actuators undergo ...
    • Buckling Pneumatic Linear Actuators Inspired by Muscle 

      Yang, Dian; Verma, Mohit Singh; So, Ju-Hee; Mosadegh, Bobak; Keplinger, Christoph; Lee, Benjamin; Khashai, Fatemeh; Lossner, Elton Garret; Suo, Zhigang; Whitesides, George McClelland (Wiley-Blackwell, 2016)
      The mechanical features of biological muscles are difficult to reproduce completely in synthetic systems. A new class of soft pneumatic structures (vacuum-actuated muscle-inspired pneumatic structures) is described that ...
    • Chirality-Dependent Friction of Bulk Molecular Solids 

      Yang, Dian; Cohen, Adam Ezra (American Chemical Society (ACS), 2014)
      We show that the solid−solid friction between bulk chiral molecular solids can depend on the relative chirality of the two materials. In menthol and 1-phenyl-1-butanol, heterochiral friction is smaller than homochiral ...
    • Negative-Pressure Soft Linear Actuator with a Mechanical Advantage 

      Yang, Dian; Verma, Mohit Singh; Lossner, Elton Garret; Stothers, Duncan Bayard; Whitesides, George McClelland (Wiley-Blackwell, 2016)
    • Noncontact orientation of objects in three-dimensional space using magnetic levitation 

      Subramaniam, A. B.; Yang, Dian; Yu, H.-D.; Nemiroski, Alex; Tricard, S.; Ellerbee, A. K.; Soh, S.; Whitesides, George McClelland (Proceedings of the National Academy of Sciences, 2014)
      This paper describes several noncontact methods of orienting objects in 3D space using Magnetic Levitation (MagLev). The methods use two permanent magnets arranged coaxially with like poles facing and a container containing ...
    • Phase-transforming and switchable metamaterials 

      Yang, Dian; Jin, Lihua; Martinez, Ramses; Bertoldi, Katia; Whitesides, George McClelland; Suo, Zhigang (Elsevier BV, 2016)
      This paper demonstrates a new soft structure that uses a meso- or macro-scale elastic instability to generate a shape-memory effect similar to that exhibited by a ferroelastic material. It demonstrates the phase transitions, ...
    • Soft Pneumatic Actuators Using Negative Pressure 

      Yang, Dian (2016-05-18)
      Soft robotics is a growing field where scientists and engineers collaborate to design machines that collaborate safely with humans (namely “collaborative robot”), and manipulate soft or delicate objects safely. Soft pneumatic ...
    • Using Magnetic Levitation for Non-Destructive Quality Control of Plastic Parts 

      Hennek, Jonathan; Nemiroski, Alex; Subramaniam, Anand; Bwambok, David K.; Yang, Dian; Harburg, Daniel V.; Tricard, Simon; Ellerbee, Audrey K.; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      Magnetic levitation (MagLev) enables rapid and non-destructive quality control of plastic parts. The feasibility of MagLev as a method to: i) rapidly assess injection-molded plastic parts for defects during process ...
