PhD Candidate in Light Controlled Variable Stiffness for Soft Robotics

ETH Zurich - April 27, 2026

PhD Position in Light Controlled Variable Stiffness for Soft Robotics

Location: 100%, Zurich, fixed-term

The Robotic Materials group is seeking a highly motivated PhD student to explore the fascinating topic of light programmable stiffness for reconfigurable soft devices and robots. This 4-year PhD position is funded by our ERC Starting Grant.

Project Background

The introduction of fiber optics in the 1970s revolutionized the telecommunications industry, replacing copper wires and playing a significant role in the Information Age. One high-bandwidth fiber optic cable can replace thousands of electrical links to transmit the same amount of information. In parallel with the flourishing fields of soft devices and robots controlled by electrical signals, soft optics is emerging as a new platform that utilizes light modulation in soft matter to encode multifunctionality in the optical path.

The first part of this project will focus on developing light-stimulated stiffness programming methods that surpass current variable stiffness benchmarks. The second part will demonstrate the application of this principle in various soft device and robot systems, illustrating reconfigurability and multifunctionality for real-world tasks.

Job Description

  • Creation of methods to program material stiffness in situ with light. Goals: high stiffness contrast (rigid-soft), fast transition (1s), and small form factor (mm scale).
  • Characterization and theoretical understanding development with multiphysics simulation.
  • Development, design, and fabrication of an active soft robotic morphing surface for reconfigurable shape/texture camouflage.
  • Development, design, and fabrication of reconfigurable soft robotic actuators for in-situ programming of actuation modality and force.
  • Demonstration as robotic/biomedical devices for real-world application through collaborations.
  • Supervise master/bachelor students.
  • Serve as a teaching assistant for the robotic materials class.

This is a full-time position that starts as soon as possible. Apply online using the form below. Only applications matching the job profile will be considered.

Profile
