Abstract

Liquid Metal-Elastomer Composites An acoustic matching layer is an essential component of an ultrasound transducer to achieve maximum ultrasound transmission efficiency. In article number 2308954, Eric J. Markvicka and co-workers control the volume loading and size of liquid metal microdroplets in a soft elastomer matrix to tailor the acoustic properties. The stretchable acoustic matching layer is integrated with a wearable ultrasound device to measure blood flow velocity in a phantom model.
