Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

Control of Actuators with Linearized Variable Stiffness

IFAC-PapersOnLine, 2019
Abstract In this paper, a new model of variable stiffness actuators (VSA) is presented. In the proposed model, the stiffness and deformation of the elastic element can be controlled independently. The structure of the model allows the use of optimal control methods, such as linear quadratic regulator, as is demonstrated in the paper. The model can be

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia

Advanced Healthcare Materials, EarlyView.
This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can

Continuous time controller based on SMC and disturbance observer for piezoelectric actuators [PDF]

, 2007
– In this work, analog application for the Sliding Mode Control (SMC) to piezoelectric actuators (PEA) is presented. DSP application of the algorithm suffers from ADC and DAC conversions and mainly faces limitations in sampling time interval.

A Data Driven Review of In Vitro Electrical and Mechanical Stimulation for Post‐Acute Phase Wound Healing

Advanced Healthcare Materials, EarlyView.
This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...
