With the release of Qortex, Quanergy is now the only LiDAR manufacturer to commercially produce an integrated [?]
Internet of Things (IoT) is the next frontier in technology and the core component bringing industrial revolution across the globe. It is entirely redefining how we use apps, devices and how people interact and connect with each other. It is turning everyday objects into data collecting gold. Internet of thing... Read more »
A key use case for Azure is as a place for working with the internet of things. A selection of IoT-focused services handle working with streams of data from any number of devices, adding machine learning and stream analytics. Most of the features you?ll need come as part of Azure?s IoT Suite, or through Cortana Analytics. In fact, the only thing that?s missing is the IoT hardware.
When a battery runs low it usually needs to be manually recharged, but new approaches could help them last indefinitely. Self-sustaining "energy neutral" batteries are being used to track animals ? and they could end up in smartphones, too.
In just a few years we might be able to blow on a disk inserted in our phones and find out what disease is brewing inside us, according to a researcher trying to develop the world's smallest breathalyser.
Escherichia coli use a transmembrane sensor protein to sense nitrate in their external environment and initiate a biochemical response. Gushchin et al. compared crystal structures of portions of the NarQ receptor that included the transmembrane helices in ligand-bound or unbound states. The structures suggest a signaling mechanism by which piston- and lever-like movements are transmitted to response regulator proteins within the cell. Such two-component systems are very common in bacteria and, if better understood, might provide targets for antimicrobial therapies.

The quantum properties of the nitrogen vacancy (NV) defect in diamond can be used as an atomic compass needle that is sensitive to tiny variations in magnetic field. Schmitt et al. and Boss et al. successfully enhanced this sensitivity by several orders of magnitude (see the Perspective by Jordan). They applied a sequence of pulses to the NV center, the timing of which was set by and compared with a highly stable oscillator. This allowed them to measure the frequency of an oscillating magnetic field (megahertz bandwidth) with submillihertz resolution. Such enhanced precision measurement could be applied, for example, to improve nuclear magnetic resonance-based imaging protocols of single molecules.

The key task in metrology is to determine physical parameters as precisely as possible given certain resources, and few problems are as important as keeping time. The history of science is closely connected with the development of the accuracy of our clocks, right up to our current standards of time: The second is defined by the frequency of an electronic transition of a cesium atom. On pages 837 and 832 of this issue, Boss et al. ( 1 ) and Schmitt et al. ( 2 ) report the independent development of nearly identical methods to greatly improve existing frequency measurements. They measured oscillating magnetic fields driven by a clock by using repeated measurements of the spin state of a nitrogen-vacancy center in diamond. It is one of those surprisingly common events in science when different research groups hit on the same idea at nearly the same time, sometimes called ?multiple independent discovery.?

The ability to sense the magnetic state of individual magnetic nano-objects is a key capability for powerful applications ranging from readout of ultradense magnetic memory to the measurement of spins in complex structures with nanometer precision. Magnetic nano-objects require extremely sensitive sensors and detection methods. We create an atomic spin sensor consisting of three Fe atoms and show that it can detect nanoscale antiferromagnets through minute, surface-mediated magnetic interaction. Coupling, even to an object with no net spin and having vanishing dipolar stray field, modifies the transition matrix element between two spin states of the Fe atom?based spin sensor that changes the sensor?s spin relaxation time. The sensor can detect nanoscale antiferromagnets at up to a 3-nm distance and achieves an energy resolution of 10 ?eV, surpassing the thermal limit of conventional scanning probe spectroscopy. This scheme permits simultaneous sensing of multiple antiferromagnets with a single-spin sensor integrated onto the surface.
Electrochemical analysis of sweat using soft bioelectronics on human skin provides a new route for noninvasive glucose monitoring without painful blood collection. However, sweat-based glucose sensing still faces many challenges, such as difficulty in sweat collection, activity variation of glucose oxidase due to lactic acid secretion and ambient temperature changes, and delamination of the enzyme when exposed to mechanical friction and skin deformation. Precise point-of-care therapy in response to the measured glucose levels is still very challenging. We present a wearable/disposable sweat-based glucose monitoring device integrated with a feedback transdermal drug delivery module. Careful multilayer patch design and miniaturization of sensors increase the efficiency of the sweat collection and sensing process. Multimodal glucose sensing, as well as its real-time correction based on pH, temperature, and humidity measurements, maximizes the accuracy of the sensing. The minimal layout design of the same sensors also enables a strip-type disposable device. Drugs for the feedback transdermal therapy are loaded on two different temperature-responsive phase change nanoparticles. These nanoparticles are embedded in hyaluronic acid hydrogel microneedles, which are additionally coated with phase change materials. This enables multistage, spatially patterned, and precisely controlled drug release in response to the patient?s glucose level. The system provides a novel closed-loop solution for the noninvasive sweat-based management of diabetes mellitus.
The development of bendable, stretchable, and transparent touch sensors is an emerging technological goal in a variety of fields, including electronic skin, wearables, and flexible handheld devices. Although transparent tactile sensors based on metal mesh, carbon nanotubes, and silver nanowires demonstrate operation in bent configurations, we present a technology that extends the operation modes to the sensing of finger proximity including light touch during active bending and even stretching. This is accomplished using stretchable and ionically conductive hydrogel electrodes, which project electric field above the sensor to couple with and sense a finger. The polyacrylamide electrodes are embedded in silicone. These two widely available, low-cost, transparent materials are combined in a three-step manufacturing technique that is amenable to large-area fabrication. The approach is demonstrated using a proof-of-concept 4 × 4 cross-grid sensor array with a 5-mm pitch. The approach of a finger hovering a few centimeters above the array is readily detectable. Light touch produces a localized decrease in capacitance of 15%. The movement of a finger can be followed across the array, and the location of multiple fingers can be detected. Touch is detectable during bending and stretch, an important feature of any wearable device. The capacitive sensor design can be made more or less sensitive to bending by shifting it relative to the neutral axis. Ultimately, the approach is adaptable to the detection of proximity, touch, pressure, and even the conformation of the sensor surface.
