MWC 2018 is not only the land of smartphone but also the place where many other unique technologies.
These include the Modius weightlifting headset, the PureLiFi-enabled Internet technology, the Labrad Labels ultrasound gesture control, and the Energous and Ossia wireless remote charging technology.
Modius weight loss headphones
Modius suppresses appetite or speeds up metabolism by projecting an electric ray into the ear for about an hour a day.
It sounds crazy, but the manufacturer promises that Modius is harmless to human health. Modius is the product of one of the founders of the company, neurology doctor Jason McKeown MD.
When wearing Modius headphones there will be a tingling sensation due to the infiltration of the bone behind the ear. There are 10 levels of discharge for the user experience.
Modius is considered a healthy weight loss method. It costs $ 250. There are 4,000 headsets sold in the market. Every day users wear just about 45 minutes.
Internet connection with light technology
PureLiFi won the top prize at the MWC 2017 last year. This year, the company continues demonstrating the Internet connectivity solution for mobile devices with light technology.
PureLiFi brings the MWC 2018 integrated signal receiver to the Dell laptop and Samsung Galaxy S5 phone case. This device allows high speed connection to the Internet.
The test shows that the video playback of Digital Trends on the Galaxy S5 is very smooth. The download speed reaches 42 Mbps.
PureLiFi technology is still pretty bulky. The miniaturization and optimization of the smartphone is expected to be completed in three years.
Gesture control by ultrasonic technology
Labrad Labs has demonstrated ultrasound technology that replaces the proximity sensor on smartphones, enabling the phone to be turned on when the hand or face approaches at close range.
This technology also appears on Xiaomi’s Mi Mix, which allows the manufacturer to maximize the thinness of the screen.
Labrad Labels adds a number of tasks using ultrasonic technology to increase the volume and selfie images.
At MWC 2018, Labrad Labels demonstrates the ability to control intelligent speakers and lights on speakers with simple gestures at short distances.
For example, clap twice to activate Alexa’s virtual assistant, clapping once to disable this function without touching the speaker or emitting a voice.
In addition, the brightness of the lights on the speakers can be controlled by holding hands. For example, when the fist is on the left side of the speaker, the lamp will light up, while holding the right side of the lamp will darken.
Wireless charging at a distance
It will be much more interesting if the smartphone is charged in the pockets, or smartwatch is charged on the user’s wrist.
The idea was made possible by Energous at MWC 2018, with a prototype of a smart speaker that acts as a transmitter, which transmits energy over sound frequencies to smartphones, smartwatches, and wireless headsets for about one meter.
The top of the speaker acts as an asymmetric charging station, much like the Qi wireless charger. Energous technology has been approved by the FCC, which means that they are safe. The first Energous product to go was the intelligent ski underwear called Skiin.
Energous has teamed up with chip maker Dialog to integrate this technology into the chipset.
Imagine a company like Apple that has an ecosystem including a speaker that acts as an energy transmitter, a remote charger for the iPhone, an Apple Watch, and an AirPod headset. This prospect could come true in the next 2-3 years.
Also at MWC 2018, Ossia Corporation demonstrated wireless charging technology at a distance. Technology used by the company can transmit energy through radio waves at 2.4 Ghz, similar to the frequency of Wi-Fi but in other channels should not conflict with each other.
At MWC 2018, technical director Hatem Zeine of Ossia demonstrated the wireless charging capabilities of the Samsung Galaxy S7.
The phone is still charging even when moving 3 meters away. Of course, as far as the transmitter is concerned, the charging intensity is reduced as much.
Imagine Ossia’s power generator on the ceiling of Starbucks. When you walk in, your phone or smartwatch will automatically charge the battery without you having to do anything.
Ossia also exhibits an eternal battery that is the size of a standard AA battery but can be recharged wirelessly at long distances and free from bottlenecks over time as there is no need for chemical reactions inside.
Ossia’s technology has not been approved by the FCC, but Hatem Zeine is confident they will achieve that. The company has worked with a number of manufacturers on integrating this technology into their chipsets and mobile devices.
