Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Grounding Large Language Models for Robot Task Planning Using Closed‐Loop State Feedback

Advanced Robotics Research, EarlyView.
BrainBody‐Large Language Model (LLM) introduces a hierarchical, feedback‐driven planning framework where two LLMs coordinate high‐level reasoning and low‐level control for robotic tasks. By grounding decisions in real‐time state feedback, it reduces hallucinations and improves task reliability.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Design and comparison of quadratic boost and double cascade boost converters with boost converter

2017 14th International Multi-Conference on Systems, Signals & Devices (SSD), 2017
Basically, the output voltage in renewable energy sources is improved using the boost converter, which is the key part in a photovoltaic chain. In this converter, the switching frequency is limited; hence the output voltage is reduced. To overcome this problem, two topologies are proposed; the quadratic boost converter results by combining the ...

Ltspice Analysis of Double- Inductor Quadratic Boost Converter in Comparison with Quadratic Boost and Double Cascaded Boost Converter

2021 12th International Conference on Computing Communication and Networking Technologies (ICCCNT), 2021
A step up converter is a main component of a micro-grid system, is used to increase the system's voltage. The use of a standard boost converter in high gain applications is not a practical technique upper range of voltage cannot be created and the duty ratio of the switch has to be higher, resulting in significant losses as well as poor efficiency. Due

Qualitative dynamics of the boost converter

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
This work qualitatively analyzes the dynamics of a current programmed mode boost converter operating in continuous conduction mode. The analysis starts with a two-dimensional (2D) map. It proceeds via center manifold theory to a one-dimensional (1D) map. C-bifurcation analysis is applied to the 1D map.
