Continuous imaging of internal organs over days could provide crucial information about health and diseases enable insights into developmental biology. We report a bioadhesive ultrasound (BAUS) device that consists thin rigid probe robustly adhered to the skin via couplant made soft, tough, antidehydrating, hydrogel-elastomer hybrid. The BAUS provides 48 hours continuous diverse organs, including blood vessels, muscle, heart, gastrointestinal tract, diaphragm, lung. diagnostic monitoring...
Ultrasound adds the third dimension to wearable sensors.
Serial assessment of the biomechanical properties tissues can be used to aid early detection and management pathophysiological conditions, track evolution lesions evaluate progress rehabilitation. However, current methods are invasive, only for short-term measurements, or have insufficient penetration depth spatial resolution. Here we describe a stretchable ultrasonic array performing serial non-invasive elastographic measurements up 4 cm beneath skin at resolution 0.5 mm. The conforms human...
Acute liver failure (ALF) is a critical medical condition defined as the rapid development of hepatic dysfunction. Conventional ultrasound elastography cannot continuously monitor stiffness over course rapidly changing diseases for early detection due to requirement handheld probe. In this study, we introduce wearable bioadhesive (BAUS-E), which can generate acoustic radiation force impulse (ARFI) induce shear waves continuous monitoring modulus changes. BAUS-E contains 128 channels with...
Abstract Organic–inorganic hybrid perovskites have demonstrated tremendous potential for the next‐generation electronic and optoelectronic devices due to their remarkable carrier dynamics. Current studies are focusing on polycrystals, since controlled growth of device compatible single crystals is extremely challenging. Here, first chemical epitaxial crystal CH 3 NH PbBr with locations, morphologies, orientations, using combined strategies advanced microfabrication, homoepitaxy, low...
Full-body, continuous wearable ultrasound will benefit health care and biomedical research. Seven key obstacles must first be overcome.
Light scattering in biological tissue presents a significant challenge for deep vivo imaging. Our previous work demonstrated the ability to achieve optical transparency live mice using intensely absorbing dye molecules, which created red spectrum while blocking shorter-wavelength photons. In this paper, we extend capability across entire visible by employing molecules with strong absorption ultraviolet and sharp edges that rapidly decline upon entering spectrum. This new color-neutral...
Significance High-resolution multipoint simultaneous structure–function analysis is becoming of great interest in a broad spectrum fields for deciphering multiscale dynamics, especially biophysics and materials science. However, current techniques are limited terms versatility, resolution, throughput, biocompatibility. Here, multifunctional imaging platform introduced that shows high sensitivity, minimum cross-talk, variety probe-based sensing. This demonstrated by parallel multiparametric...
The traditional ultrasonic computerized tomography (UCT) method needs numerous measurements to detect the inside conditions of concrete. Considering damage is sparsely distributed in reinforced concrete, compressive sampling (CS) applied advance UCT at both measurement stage and imaging localize part structure. proposed detection algorithm requires much fewer compared with same accuracy. In stage, pitch–catch paths are randomly selected capture travel time wave from one side other dense net....
Spinal cord neuromodulation can restore partial to complete loss of motor functions associated with neuromotor disease and trauma. Current technologies have made substantial progress but limitations as dorsal epidural or intraspinal devices that are either remote ventral neurons subject surgical intervention in the spinal tissue. Here, we describe a flexible stretchable stimulator design nanoscale thickness be implanted by minimally invasive injection through polymeric catheter target space...
This paper proposes a new way for guided wave structural health monitoring using in-plane shear (d36 type) piezoelectric wafer active sensors phased arrays. Conventional arrays based on inducing into specific Lamb modes (d31 has already widely used of the thin-wall structures. Rather than modes, induces horizontal (SH) waves. The SH waves are distinct with simple waveform and less additional converted zero symmetric mode (SH<sub>0</sub>) is non-dispersive. In this paper, advantage wafers...

Traditional ultrasonic computerized tomography (UCT) is heavy task to detect damages object for numerous measuring times huge cost manual labor. However, utilizing proposed this can effectively overcome great disadvantage, essence application Compressive Sampling(CS) detection selectively choose small quantity path number total measurements. Due sparsity concrete structure, usage CS available....
