Voltage-driven shape-memory actuators enable multistable micropositioners, origami metamaterials, and memory arrays.
Autonomous robots-systems where mechanical actuators are guided through a series of states by information processing units to perform predesigned function-are expected revolutionize everything from health care transportation. Microscopic robots poised for similar revolution in fields medicine environmental remediation. A key hurdle developing these microscopic is the integration systems, particularly electronics fabricated at commercial foundries, with microactuators. Here, we develop such...
Significance The smallest objects resolvable by the unaided human eye are approximately 100 μm in size. This limit sets a boundary between familiar and microscopic, visible invisible worlds. Here we describe fabrication of tiny wireless sensors, optical integrated circuits (OWICs) for circuits. OWICs truly microscopic size, to naked at best as tiny, undifferentiated speck, yet they can sense their environment report information back macroscopic world. They have potential applications many...
Abstract Electronically controllable actuators have shrunk to remarkably small dimensions, thanks recent advances in materials science. Currently, multiple classes of can operate at the micron scale, be patterned using lithographic techniques, and driven by complementary metal oxide semiconductor (CMOS)-compatible voltages, enabling new technologies, including digitally controlled micro-cilia, cell-sized origami structures, autonomous microrobots onboard electronics. This field is poised...
Small-scale optical and mechanical components machines require control over three-dimensional structure at the microscale. Inspired by analogy between paper two-dimensional materials, origami-style folding of atomically thin materials offers a promising approach for making microscale structures from thinnest possible sheets. In this Letter, we show that monolayer molybdenum disulfide (MoS2) can be folded into shapes technique called capillary origami, in which surface tension droplet drives...
Maxillofacial fractures in pediatric trauma patients require significant force and frequently are associated with concomitant injuries. The anatomic developmental differences between the adult child that impact patterns of injury also affect management outcomes. aim this study was to analyze fracture location, mechanism, injuries as well methods surgical treatment outcomes, improve patient population. A retrospective review conducted maxillofacial presenting a level-1 center during an 8-year...
Biological systems convert chemical energy into mechanical work by using protein catalysts that assume kinetically controlled conformational states. Synthetic chemomechanical catalysis have been reported, but they are slow, require high temperatures to operate, or indirectly perform harnessing reaction products in liquids (e.g., heat protons). Here, we introduce a bioinspired strategy for gas-phase transduction sequences the elementary steps of catalytic reactions on ultrathin (<10 nm)...
Nipple-areola reconstruction represents the completion of breast restorative process and is associated with significant positive psychological implications. While factors such as medical comorbidities, smoking status, radiation therapy have been shown to be an increase in complications following reconstruction, their impact on nipple remains largely unaddressed literature. An IRB-approved, retrospective review 472 patients who underwent at Wake Forest University over a 15-year period was...
An array of micrometer-scale pixels MoS 2 works as a fluorescent “redox screen” to visualize redox molecule concentration.
Abstract We have developed a fabrication process that can be used to build millions of microscopic, electronically-integrated robots. Our procedure includes steps for building silicon microelectronics, components actuation, encapsulation steps, and releasing the robots into aqueous environments. Each step is carried out massively in parallel, allowing us over million on single 4-inch wafer. Broadly, new actuators protocols presented here offer generic platform make wide range silicon-based,...
Brushless Direct Current (BLDC) actuators are recognized for their combined torque capabilities, precision control, and operational versatility, especially in regards to smaller size. Actuators of this caliber commonly implemented high-performance industrial robotic arms, development exoskeletal technologies, quadrupedal platforms. Professionally-developed brushless available the commercial sector deliver performance, however at a significant monetary expense. Our aim is produce...
