The number of sensors all around us is rapidly increasing. From smartwatches and heart-rate monitors to smart refrigerators and thermostats, everything is measured and tracked. All these sensors for the Internet of Things (IoT) devices need batteries and they consume a lot of power. The project ZERO (Towards Energy Autonomous Systems for IoT) aims to create efficient devices that exploit the energy already around them, such as light, vibration and heat.

With over 60 million American adults owning a smart speaker, human-to-machine conversation have largely become a part of a daily ritual. Though these exchanges are seemingly simple to the user, the complex technology that backs the interactions is powered by artificial intelligence, machine learning, and speech recognition. These modern machines are only continuing to grow in popularity, and for many Americans, voice recognition technology is becoming as natural as owning a smartphone. The user interfaces that drive the functionality of smart speakers have brought new and improved convenience to modern-day Americans. By the same token, this capability has the potential to alleviate burdens from the operations of our nation’s first responders.

Smart speakers—think, an Amazon Alexa or a Google Home—offer a wide variety of capabilities to help free up both our time and our hands. We can hear the morning news while brushing our teeth, ask for a weather report while picking out a coat, and set a timer for the oven while handling two hot pans at once. According to Voicebot.ai, Alexa is supporting more than 100,000 skills worldwide, but one task it hasn’t mastered is determining user location in the home.

Researchers at the University of Essex, UESTC-China and ZTE have recently introduced a scheme for the deployment of hybrid access points (H-APs), which could simultaneously enable wireless information transfer (WIT) and wireless energy transfer (WET) in smart cities. This unique scheme, presented in a paper pre-published on arXiv, uses a mobility model of grid-based streets in urban environments to represent the movements of users navigating a city.
