Postdoc Position in Light Multiplexed, Fiber-Based Artificial Sensorimotor Network

100%, Zurich, Fixed-Term

The Robotic Materials group is seeking a highly motivated postdoctoral researcher for the innovative project on light multiplexed artificial sensorimotor networks. This 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 significantly contributing to the Information Age. A single high-bandwidth fiber optic cable can replace thousands of electrical links to transmit the same amount of information. Parallel to the evolving fields of soft devices and electrical signal-controlled robots, soft optics has emerged as a new paradigm that utilizes light modulation in soft materials to encode multifunctionalities in the optical pathway.

This project aims to enhance both actuation and sensing capabilities using light. We will create an artificial sensorimotor network with densely distributed actuators and sensors that mimic biological neuromusculature. The initial phase will focus on developing a single soft optical fiber embedded with distributed multimodal actuators that are also self-sensing. The second phase will explore the coordinated behavior of these muscle bundles to enable complex, adaptive, and efficient movements.

Job Description

• Develop self-sensing methods based on existing light actuators, utilizing transducers that provide both actuation and sensing, controlled by onboard optoelectronics.
• Design and microfabricate a soft optical fiber embedded with transducers configured for multiple modalities, incorporating individual addressability through light multiplexing, leveraging the group's expertise.
• Demonstrate advanced robotic functions using the single artificial neuromuscular fiber created from distributed multimodal actuators and sensors.
• Create grouped neuromuscular bundles with an extremely high functional density, approaching biological orders of magnitude.
• Investigate emergent coordinated bundle behavior and motion patterns derived from biologically inspired redundancy, collaborating with control and learning experts.
• Supervise master’s and bachelor’s students.
• Serve as a teaching assistant for the robotic materials class.
