Acoustic Properties of Stretchable Liquid Metal‐Elastomer Composites for Matching Layers in Wearable Ultrasonic Transducer Arrays

Ethan J. Krings,
Benjamin D. Hage,
Sequoia L. Truong
et al.

Abstract: Ultrasound is a safe, noninvasive diagnostic technique used to measure internal structures such as tissues, organs, and arterial and venous blood flow. Skin‐mounted wearable ultrasound devices can enable long‐term continuous monitoring of patients to provide solutions to critical healthcare needs. However, stretchable ultrasound devices that are composed of ultrasonic transducers embedded in an elastomer matrix are incompatible with existing rigid acoustic matching layers, leading to reduced energy transmissio… Show more

“…244 However, the use of conventional inflexible matching layers is not feasible in the realm of conformal electronics. To address this concern, scientists have investigated the incorporation of LM fillers into elastomeric matrices, 245 which affords the ability to fine-tune the acoustic impedance of soft materials to achieve a high acoustic impedance for the wearable ultrasound device.…”
