Google Ditches the Screen With the New Fitbit Air (2026)

WIRED

Powered by Gemini and designed around simplicity, the new Fitbit Air could be a compelling fitness tracker alternative to Whoop. Five years after acquiring Fitbit, and three years since it released the Charge 6, Google is finally expanding into a new phase of fitness tracking . With its screen-free design, the new Fitbit Air could be the first device to threaten Whoop's grip on this category, thanks in large part to Google's intuitive, user-friendly software. The Fitbit Air is Google's most minimalist wearable yet. There's no AMOLED display, no haptic side button, and none of the visual feedback loops that have defined Fitbit devices (and most fitness trackers) for years.


Evaluating probabilistic and data-driven inference models for fiber-coupled NV-diamond temperature sensors

arXiv.org Artificial Intelligence

To meet such disparate measurement needs, a variety of temperature sensors have been developed. Although these devices vary greatly in their cost, size, weight and complexity, they almost all rely on well-established measurements of transport properties to infer temperature. Legacy technologies like platinum resistance thermometers and negative temperature coefficient thermistors have been relied upon for over a century to provide accurate and reproducible measurements over a broad range of temperature [2-4]. However, these sensors are prone to drift and require frequent re-calibrations to ensure high accuracy in critical use-cases resulting in increase cost of sensor ownership. In recent years, there has been a growing interest in developing alternative sensor technologies that can overcome the limitations of traditional technologies. The past decade has seen a burst of activity in nanophotonics [5], quantum optomechanics [6] and noise thermometry [7]. These technologies leverage telecomm industry's vast economies of scale along with precision measurement expertise developed for frequency metrology to enable fit-for-purpose, cost-effective measurement solutions. Development of an ultra-stable temperature sensor that shows minimal drift over decadal time spans or a field-deployable thermodynamic temperature sensor, likely based on quantum technologies could disrupt the calibration-centered metrology ecosystem of today [4, 5].


Prediction of Wort Density with LSTM Network

arXiv.org Artificial Intelligence

Many physical target values in technical processes are error-prone, cumbersome, or expensive to measure automatically. One example of a physical target value is the wort density, which is an important value needed for beer production. This article introduces a system that helps the brewer measure wort density through sensors in order to reduce errors in manual data collection. Instead of a direct measurement of wort density, a method is developed that calculates the density from measured values acquired by inexpensive standard sensors such as pressure or temperature. The model behind the calculation is a neural network, known as LSTM.


Improving Building Temperature Forecasting: A Data-driven Approach with System Scenario Clustering

arXiv.org Artificial Intelligence

Heat, Ventilation and Air Conditioning (HVAC) systems play a critical role in maintaining a comfortable thermal environment and cost approximately 40% of primary energy usage in the building sector. For smart energy management in buildings, usage patterns and their resulting profiles allow the improvement of control systems with prediction capabilities. However, for large-scale HVAC system management, it is difficult to construct a detailed model for each subsystem. In this paper, a new data-driven room temperature prediction model is proposed based on the k-means clustering method. The proposed data-driven temperature prediction approach extracts the system operation feature through historical data analysis and further simplifies the system-level model to improve generalization and computational efficiency. We evaluate the proposed approach in the real world. The results demonstrated that our approach can significantly reduce modeling time without reducing prediction accuracy.

Lifetime-configurable soft robots via photodegradable silicone elastomer composites

arXiv.org Artificial Intelligence

Developing soft robots that can control their own life-cycle and degrade on-demand while maintaining hyper-elasticity is a significant research challenge. On-demand degradable soft robots, which conserve their original functionality during operation and rapidly degrade under specific external stimulation, present the opportunity to self-direct the disappearance of temporary robots. This study proposes soft robots and materials that exhibit excellent mechanical stretchability and can degrade under ultraviolet (UV) light by mixing a fluoride-generating diphenyliodonium hexafluorophosphate (DPI-HFP) with a silicone resin. Spectroscopic analysis revealed the mechanism of Si-O-Si backbone cleavage using fluoride ion (F-), which was generated from UV exposed DPI-HFP. Furthermore, photo-differential scanning calorimetry (DSC) based thermal analysis indicated increased decomposition kinetics at increased temperatures. Additionally, we demonstrated a robotics application of this composite by fabricating a gaiting robot. The integration of soft electronics, including strain sensors, temperature sensors, and photodetectors, expanded the robotic functionalities. This study provides a simple yet novel strategy for designing lifecycle mimicking soft robotics that can be applied to reduce soft robotics waste, explore hazardous areas where retrieval of robots is impossible, and ensure hardware security with on-demand destructive material platforms.


Multidimensional analysis using sensor arrays with deep learning for high-precision and high-accuracy diagnosis

arXiv.org Artificial Intelligence

In the upcoming years, artificial intelligence (AI) is going to transform the practice of medicine in most of its specialties. Deep learning can help achieve better and earlier problem detection, while reducing errors on diagnosis. By feeding a deep neural network (DNN) with the data from a low-cost and low-accuracy sensor array, we demonstrate that it becomes possible to significantly improve the measurements' precision and accuracy. The data collection is done with an array composed of 32 temperature sensors, including 16 analog and 16 digital sensors. All sensors have accuracies between 0.5-2.0$^\circ$C. 800 vectors are extracted, covering a range from to 30 to 45$^\circ$C. In order to improve the temperature readings, we use machine learning to perform a linear regression analysis through a DNN. In an attempt to minimize the model's complexity in order to eventually run inferences locally, the network with the best results involves only three layers using the hyperbolic tangent activation function and the Adam Stochastic Gradient Descent (SGD) optimizer. The model is trained with a randomly-selected dataset using 640 vectors (80% of the data) and tested with 160 vectors (20%). Using the mean squared error as a loss function between the data and the model's prediction, we achieve a loss of only 1.47x10$^{-4}$ on the training set and 1.22x10$^{-4}$ on the test set. As such, we believe this appealing approach offers a new pathway towards significantly better datasets using readily-available ultra low-cost sensors.
