The team suggested two software mitigation measures for operating system providers: tightening up permissions and reducing the precision and speed of the sensors. First, they recommend restricting access to the ambient light sensor by allowing users to approve or deny those requests from apps. To fur...
With these devices, the sample is placed directly onto the image sensor. The sample is then illuminated by an external light source in a particular geometry so as to create a series of holograms, which are captured by the image sensor. Subsequent image processing translates the raw holograms ...

We analyzed sleep data from over 1 million nights captured by a consumer wearable sleep-tracking device over 3 years in the Chinese population. Our findings show that both short- and long-term exposure to ambient air pollution is associated with sleep characteristics, among which the cumulative ef...
(based on your iPhone’s home / away status), when a sensor detects something (motion or smoke), and/or when another device is controlled (such as a door locked). The different between Scenes and Automations is that Scenes require you to trigger them by voice or touch; Automations happen...

we propose a new device identification approach considering the challenges of the smartphone identification process. It utilizes the sensor calibration-based identity as a device fingerprint and the Blockchain technology to manage the fingerprint. The comparisons with related solutions showed that our propo...

Solar cells that operate efficiently under indoor lighting are of great practical interest as they can serve as electric power sources for portable electronics and devices for wireless sensor networks or the Internet of Things. Here, we demonstrate a dye-sensitized solar cell (DSC) that achieves ve...
Control over the intensity, shape, direction and phase of coherent light is essential in numerous fields, from gravitational wave astronomy, quantum metrology and ultrafast sciences to semiconductor fabrication. Modern photonics, however, can involve parameter regimes where the wavelength or high optical ...
