    • 25th Anniversary Article: A Soft Future: From Robots and Sensor Skin to Energy Harvesters 

      Bauer, Siegfried; Bauer-Gogonea, Simona; Graz, Ingrid; Kaltenbrunner, Martin; Keplinger, Christoph; Schwödiauer, Reinhard (BlackWell Publishing Ltd, 2013)
      Scientists are exploring elastic and soft forms of robots, electronic skin and energy harvesters, dreaming to mimic nature and to enable novel applications in wide fields, from consumer and mobile appliances to biomedical ...
    • 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 ...
    • Charge localization instability in a highly deformable dielectric elastomer 

      Lu, Tongqing; Keplinger, Christoph; Arnold, Nikita; Bauer, Siegfried; Suo, Zhigang (AIP Publishing, 2014)
      This paper shows that a highly deformable capacitor made of a soft dielectric and two conformal electrodes can switch between two states discontinuously, by a first-order transition, as the total charge varies gradually. ...
    • Inkjet Printing of Conductive Inks with High Lateral Resolution on Omniphobic “R F Paper” for Paper-Based Electronics and MEMS 

      Lessing, Joshua; Glavan, Ana C; Walker, S. Brett; Keplinger, Christoph; Lewis, Jennifer; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      The use of omniphobic “fluoroalkylated paper” as a substrate for inkjet printing of aqueous inks that are the precursors of electrically conductive patterns is described. By controlling the surface chemistry of the paper, ...
    • Ionic skin 

      Sun, Jeong-Yun; Keplinger, Christoph; Whitesides, George McClelland; Suo, Zhigang (Wiley-Blackwell, 2014)
      Electronic skins (i.e., stretchable sheets of distributed sensors) report signals using electrons, whereas natural skins report signals using ions. Here, ionic conductors are used to create a new type of sensory sheet, ...
    • Natural rubber for sustainable high-power electrical energy generation 

      Kaltseis, Rainer; Keplinger, Christoph; Adrian Koh, Soo Jin; Baumgartner, Richard; Goh, Yu Feng; Ng, Wee Hoe; Kogler, Alexander; Tröls, Andreas; Foo, Choon; Suo, Zhigang; Bauer, Siegfried (Royal Society of Chemistry (RSC), 2014)
      Clean, renewable and abundant sources of energy, such as the vast energy of ocean waves, are untapped today, because no technology exists to convert such mechanical motions to electricity economically. Other sources of ...
    • Pneumatic Networks for Soft Robotics that Actuate Rapidly 

      Mosadegh, Bobak; Polygerinos, Panagiotis; Keplinger, Christoph; Wennstedt, Sophia W; Shepherd, Robert F.; Gupta, Unmukt; Shim, Jongmin; Bertoldi, Katia; Walsh, Conor J; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      Soft robots actuated by pressurization and inflation of a pneumatic network (a “pneu-net”) of small channels in elastomeric materials are appealing for their ability to produce sophisticated motions with simple controls. ...
    • Soft Actuators and Robots that Are Resistant to Mechanical Damage 

      Martinez, Ramses; Glavan, Ana C; Keplinger, Christoph; Oyetibo, Alexis I.; Whitesides, George McClelland (Wiley-Blackwell, 2014)
      This paper characterizes the ability of soft pneumatic actuators and robots to resist mechanical insults that would irreversibly damage or destroy hard robotic systems—systems fabricated in metals and structural polymers, ...
    • Stretchable Conductive Composites Based on Metal Wools for Use as Electrical Vias in Soft Devices 

      Lessing, Joshua; Morin, Stephen A.; Keplinger, Christoph; Tayi, Alok S.; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      Soft devices can be bent, stretched, and compressed reversibly, but conventional wires are rigid. This work describes stretchable composites that are easily fabricated with simple tools and commodity materials, and that ...
    • Stretchable, Transparent, Ionic Conductors 

      Keplinger, Christoph; Sun, Jeong Yun; Foo, Choon Chiang; Rothemund, Philipp Josef Michael; Whitesides, George M.; Suo, Zhigang (Association for the Advancement of Science, 2013)
      Existing stretchable, transparent conductors are mostly electronic conductors. They limit the performance of interconnects, sensors, and actuators as components of stretchable electronics and soft machines. We describe a ...
