Bending mechanics of cylindrical skins for morphing aerospace applications

Materials & Design, 2020
Shape-changing aerospace structures explore the trade-offs between aerodynamic performance and actuation efficiency. Herein, a morphing cylinder is optimized to minimize both its work to actuate in bending as well as radial deviations.

Flexible Thin‐Film Heater Composed of Laser‐Induced Graphene and Poly(D, L‐Lactic Acid) with Electro‐ and Photo‐Thermal Properties toward Cancer Thermotherapy

Advanced Electronic Materials, EarlyView.
This study introduces a thin‐film‐type heat‐generating device that uses laser induced graphene (LIG) on a poly(D, L‐lactic) acid film, which realizes both resistance heating by direct current application and photothermal conversion heating by near‐infrared light irradiation.

Thin‐Film Thermal Sensors on Chitosan Substrates for Sustainable Transient Electronics

Advanced Electronic Materials, EarlyView.
Fully transient thin‐film temperature sensors are realized on pure chitosan substrates using Mo‐based RTDs and a‐IGZO/Mo thermistors. The devices exhibit high sensitivity, mechanical flexibility, humidity‐aware operation, and complete dissolution in natural solvents.

Two-Dimensional Discrete Model for Buckling of Helical Springs

Procedia Structural Integrity, 2019
Abstract The classical theory of helical spring instability is based on the buckling of an equivalent column. Alternatively, more advanced methods are found in literature, involving the numerical solution of the displacement field of the helical wire.
