Researchers at the Georgia Institute of Technology unveiled an innovative way to utilize the surplus capacity of 5G networks and tackle the limitations of batteries. Using a Rotman lens-based rectifying antenna, the innovators recorded power harvesting at 28 GHz. The network efficiency is maximized by collecting all the electromagnetic energy from an antenna and supplying it into a single rectifier. The FCC has authorized 5G networks to generate immense power as compared to previous generations of Internet of Things (IoT) devices. Experiments recorded a 21-fold increase in power production that is going to pave the road for major ubiquitous IoT applications.(“Leveraging the 5G Network to Wirelessly Power IoT Devices” – Georgia Tech)


Foci, a wearable device developed after 2 decades of research that combines cognitive biometrics with Artificial Intelligence (AI) and Machine Learning (ML) to help users stay focused. It controls the mental distractions by tracking the changing emotions and uses the power of neuro-respiratory science with cognitive biometrics to help users discover when their mind performs optimally. The motion sensors in the device input breathing change in real-time and relate it with our subconscious to detect if the user is relaxed or stressed.

MIT researchers employed the tensor holography method to create 3D holograms for virtual reality. The efficient deep-learning-based method generates holograms on smartphones in real-time. Stimulated with optical setup and knowledge of deep-learning models, the team designed a convolutional neural network to emulate the way humans process visual information. The project used a huge dataset of 4,000 pairs of computer-generated images to create holograms. The photorealistic training data builds 3D holography that boosts up the development of VR and 3D printing systems. (“Using artificial intelligence to generate 3D holograms in realtime” – MIT News)


Researchers at the University of Helsinki and University of Copenhagen developed an AI-based system that reads the brain and generates personally attractive images. The adversarial neural network (GAN) and electroencephalography (EEG) technology gathers the individual responses against artificial portraits. The system enables the computer to create facial images based on individual preferences automatically by capturing the brain signals. The high-end project streamlines modeling preferences, decision-making, and identification of unconscious attitudes. (“Beauty is in the brain of the beholder” – UNIVERSITY OF HELSINKI)


Facebook Reality Labs presents a wristband that streamlines human interaction with computers. Using the electromyography (EMG) technique, sensors translate the nerve signals through the wrist into digital commands and operate the device. The band recognizes gestures through hand and finger muscles to control the Augmented Reality (AR) interface. Users do not need to type, it clicks without actually clicking the keys. The splendid updates in this band are ongoing that focus on making it more realistic and practical. (“Facebook shows off how you’ll use its neural wristbands with AR glasses” – The Verge)
