Mashup Score: 29A textile origami snake robot for rectilinear locomotion - 1 month(s) ago
Integrating insights from snake biology into soft robotics holds promise for developing adaptive autonomous robots. These innovations can have applications in areas such as search-and-rescue missions, field inspection operations, and space exploration, especially in scenarios demanding navigation through confined spaces where body flexion is not feasible. In this work, the authors learned snakes’ rectilinear locomotion and leveraged origami to design textile-based actuators to create a lightweight, soft robot for friction-assisted locomotion across diverse terrains.

Mashup Score: 19An intrinsically stretchable power-source system for bioelectronics - 1 month(s) ago
This work demonstrates a fully stretchable and integrated power source, consisting of a triboelectric nanogenerator (TENG), a polymeric four-transistor rectifier, and a supercapacitor, designed to harvest stretching-type mechanical energy from tissue/organ motions. The TENG, featuring tissue-like softness, high stretchability, and high output power, has been successfully tested as an implantable harvester on a porcine heart. The fully integrated power source can operate conformably on the human body, offering sustainable energy for wearable and implantable electronics.

Mashup Score: 18Mechanically programming anisotropy in engineered muscle with actuating extracellular matrices - 1 month(s) ago
Living cells embedded in an extracellular matrix sense and respond to mechanical stimuli in their environment. We have developed a method for magnetic matrix actuation (MagMA) enabling dynamic, non-invasive mechanical stimulation of tissues. As a proof-of-concept demonstration, we show that MagMA programs the alignment of skeletal muscle fibers with downstream functional effects on the global synchrony of muscle contraction. Precisely controlling muscle morphology and force generation is of significant importance in applications ranging from regenerative medicine to robotics.

Mashup Score: 28Biorobotic hybrid heart as a benchtop cardiac mitral valve simulator - 1 month(s) ago
We introduce a highly realistic model of a beating heart that accurately replicates mitral valve function in both health and disease. Our simulator integrates real heart tissue with soft robotic cardiac muscles to achieve life-like motion and evaluate devices designed for mitral valve repair. Utilizing innovative soft robotic technology, we mimic the biomechanics of the heart including the motion, pressure generation, and flow, closely resembling a native heart. With this setup, we can acquire real-time performance data, enable visualization during procedures, and seamlessly integrate with medical imaging tools.
