The Robotic Materials group is looking for a highly motivated postdoc for the topic of light multiplexed artificial sensorimotor network. This position is funded by our ERC Starting Grant.

The introduction of fiber optics in the 1970s has revolutionized the telecommunications industry upon the replacement of copper wires and played a major role in the advent of the Information Age - One high bandwidth fiber optic cable can replace thousands of electrical links to transmit the same amount of information. As a parallel to the thriving fields of soft devices and robots controlled by electrical signals, soft optics is emerging as a new platform that uses the modulation of light in soft matter to encode multifunctionalities in the optical path. 

The focus of this project is to expand both actuation and sensing capacities with light. The project will create an artificial sensorimotor network with densely distributed actuators and sensors similar to the biological neuromasculature. The first part of the project will develop a single soft optical fiber with distributed multimodal actuators that are also self-sensing. The second part will study grouped behavior of these “muscle bundles” to enable muscle coordination for complex/adaptive/efficient movements.

• Based on existing light actuators in our group, develop self-sensing methods where the transducer serves both for actuation and sensing, and is feedback controlled with onboard optoelectronics
• Design and microfabrication of a soft optical fiber distributed with such transducers configured for multiple modalities, and enable individual addressability through light multiplexing, based on the group’s expertise
• Demonstrate the single artificial neuromuscular fiber for advanced robotic functions arising from the distributed and multimodal actuators and sensors
• In the second part, create grouped neuromuscular bundles with extremely high functional density approaching orders of magnitude of biology
• Investigate emergent coordinated bundle behavior and motion patterns arising from biologically similar redundancy with collaborations of control and learning
• Demonstrate for advanced robotic functions
• Supervise master/bachelor students 
• Teaching assistant for the robotic materials class
