DESCRIPTION:Jisung Park (FLEXLAB\, EPFL)\nAbstract: Soft mechanical syst
 ems often face challenges such as limited force output and slow response t
 imes due to their intrinsic material properties. In this talk\, we present
  an Elasto-Magnetic Instability (EsMI) that overcomes these limitations by
  combining magnetic attraction with elastic tension to create robust bista
 ble dynamics. We demonstrate this principle through a Coupled Elasto-Magne
 tic Vibration (C-EsMV) system\, which achieves significant motion amplific
 ation and force output compared to non-coupled systems across a wide frequ
 ency range. By analyzing the delicate balance between magnetic and elastic
  forces\, we establish scalable design principles applicable to various so
 ft robotic configurations. Furthermore\, the system exhibits unique inerti
 al hysteresis\, enabling programmable dual-mode (volatile and non-volatile
 ) mechanical memory. These findings highlight the potential of harnessing 
 instabilities to develop programmable\, adaptive\, and high-performance so
 ft actuators for complex environments.\nBio: Ji-Sung Park is a Postdoctor
 al Researcher at the École Polytechnique Fédérale de Lausanne (EPFL)\, 
 working in the Flexible Structures Laboratory (fleXLab) under the supervis
 ion of Professor Pedro M. Reis. He received his B.S. in Mechanical Enginee
 ring from Seoul National University (SNU) in 2019 \, followed by an integr
 ated M.S. and Ph.D. in 2025 under Professor Ho-Young Kim. His academic bac
 kground spans across microfluidics\, soft matter physics\, and mechanical 
 instabilities.
