We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto skin leads conformal contact adequate adhesion based on van der Waals interactions alone, in a manner is mechanically invisible user. describe incorporating electrophysiological, temperature, strain sensors, as well transistors, light-emitting diodes,...
Successful integration of advanced semiconductor devices with biological systems will accelerate basic scientific discoveries and their translation into clinical technologies. In neuroscience generally, in optogenetics particular, the ability to insert light sources, detectors, sensors, other components precise locations deep brain yields versatile important capabilities. Here, we introduce an injectable class cellular-scale optoelectronics that offers such features, examples unmatched...
The sensitivity of a nanoscale crack-based sensor is enhanced markedly by modulating the crack depth. crack-depth-propagated exhibits ≈16 000 gauge factor at 2% strain and superior signal-to-noise ratio ≈35, which facilitates detection target signals for voice-pattern recognition.
Abstract Materials and fabrication procedures are described for bioresorbable transistors simple integrated circuits, in which the key processing steps occur on silicon wafer substrates, schemes compatible with methods used conventional microelectronics. The approach relies an unusual type of insulator to yield devices that exploit ultrathin sheets monocrystalline semiconductor, thin films magnesium electrodes interconnects, dioxide oxide dielectrics, silk substrates. A range component...
Abstract Owing to the growing demand for highly integrated electronics, anisotropic heat dissipation of thermal management material is a challenging and promising technique. Moreover, satisfy needs advancing flexible stretchable electronic devices, maintaining high conductivity during deformation materials at issue. Presented here an effective assembly technique realize continuous array boron nitride (BN) nanosheets on tetrahedral structures, creating 3D paths with deformable electronics....
Bioelectronics needs to continuously monitor mechanical and electrophysiological signals for patients. However, the always include artifacts by patients' unexpected movement (such as walking respiration under approximately 30 hertz). The current method remove them is a signal process that uses bandpass filter, which may cause loss. We present an unconventional filter material-viscoelastic gelatin-chitosan hydrogel damper, inspired viscoelastic cuticular pad in spider-to dynamic noise...
Fabrics are widely used in hospitals and many other settings for bedding, clothing, face masks; however, microbial pathogens can survive on surfaces a long time, leading to transmission. Coatings of metallic particles fabrics have been eradicate pathogens. However, current metal particle coating technologies encounter numerous issues such as nonuniformity, processing complexity, poor adhesion. To overcome these issues, an easy-to-control straightforward method is reported coat wide range by...
Abstract Kirigami, a traditional paper‐cutting art, is promising method for creating mechanically robust circuitry unconventional devices capable of extreme stretchability through structural deformation. In this study, design approach expanded upon by introducing Liquid Metal based Elastic Kirigami Electrodes (LM‐eKE) in which kirigami‐patterned soft elastomers are coated with eutectic gallium‐indium (EGaIn) alloy. Overcoming the mechanical and electrical limitations previous efforts...
Abstract Tactile function is essential for human life as it enables us to recognize texture and respond external stimuli, including potential threats with sharp objects that may result in punctures or lacerations. Severe skin damage caused by severe burns, cancer, chemical accidents, industrial accidents the structure of tissue well nerve system, resulting permanent tactile sensory dysfunction, which significantly impacts an individual’s daily life. Here, we introduce a fully-implantable...
Abstract Electrophysiology, exploring vital electrical phenomena in living organisms, anticipates broader integration into daily life through wearable devices and epidermal electrodes. However, addressing the challenges of electrode durability motion artifacts is essential to enable continuous long‐term biopotential signal monitoring, presenting a hurdle for its seamless implementation life.
