Spring and Power in Hovering Ornithopters
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Electropneumatic Oscillators Using Nonlinear Inflatables
In animals, self‐oscillations are essential to coordinate locomotion and other bodily functions. By combining hysteretic membranes with a resistive strain sensor, an electropneumatic self‐oscillator with an oscillation frequency that directly depends upon geometric parameters in the fluidic domain is introduced.

This article proposes a soft wearable robot (WeaRo) to assist workers while executing manual handling tasks. With its innovative design, the WeaRo effectively assists multiple body parts during manual handling tasks while using a single motor. Furthermore, the components of the WeaRo are assembled onto a fabric‐based suit, ensuring high performance and

A Wearable Soft Actuator for Directional Tactile Stimulation: Design and Testing
A wearable actuator able to produce directional tactile stimulation is obtained by embedding a planar shape memory spring in silicone matrix. The matrix is designed taking into account skin characteristics and leveraging its multifunctionality: it acts as a bias load, improves the thermal behavior of the spring and wearability.

This work presents a novel flexible tactile sensor based on the unconventional reversible contact behavior between liquid metal droplets (LMDs), with high‐pressure sensitivity and a broad working range. The 2‐LMD‐based sensor is capable of monitoring human motion and physiological signals, while electrical impedance tomography enables precise shape and

A machine learning approach utilizes micro inertial measurement units (μIMUs) for noninvasive sarcopenia screening through a sit‐to‐stand test. With 53 older participants wearing IMUs, 510 features are extracted across four motion phases. Five algorithms (support vector machine, K‐nearest neighbors, decision tree, linear discriminant analysis, and ...

This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.
