Synergistic Microcrack Engineering and Auxetic Metamaterials for Enhanced Sensitivity in Stretchable Strain Sensors

Advanced Materials Technologies, EarlyView.
A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.

Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

Advanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

MEMS‐Based Magnetoelectric Antennas for Wireless Power Transmission in Brain‐Implantable Devices

Advanced Materials Technologies, EarlyView.
Magnetoelectric (ME) antennas allow the minimization of the invasiveness of brain implantable devices, via powering wirelessly systems able to actuate neural tissue. In order to achieve the necessary power efficiency transmission, the choice of the materials and the system assembly is vital.

Light Induced Training of 3D Printed Mechanical Metamaterials

Advanced Materials Technologies, EarlyView.
A new 3D‐printable material that stiffens under UV light is integrated into the architecture of mechanical metamaterials to realize trainable systems. Local stiffening amplified by rational design enables closed‐loop systems with tunable properties guided by UV irradiation. The resulting structures gradually adapt shape or resistance, demonstrating how
