Could we charge our phones using SWEAT? Temporary tattoo uses chemicals in perspiration to generate energy
- The patch works by detecting lactate, which is naturally found in sweat
- The more intense the exercise, the more lactate the body produces
- Sensors contain an enzyme that strips electrons from lactate
- This generates a weak electrical current which powers a biobattery
- Currently, the battery produces around 70 microWatts per square cm of skin
- But researchers are working on a way to harness more energy to charge larger devices such as phones or tablets

Why You Still Need An MP3 Player
Only five or ten years ago MP3 players were the most popular devices for listening to music, but as mobile phones became more and more advanced, MP3 players started to lose their popularity. However, there are still plenty of reasons to choose an MP3 player over a music app in your smartphone. You can buy MP3 players and lots of other electronics in Nigeria at unbelievably low prices by simply following this link: https://jiji.ng/electronics
Low cost gadget
Even the latest MP3 player model is still cheaper than a mid-range smartphone, so if you often break or lose your device, an MP3 player can become your low-risk investment. For example, it may turn out that replacing the screen on your iPhone costs as much as a new iPod, so dropping your device on the ground can have different consequences depending on which gadget you prefer.
Take the most out of your music collection
Most music fans have huge collections of MP3 files on their computer – they can be downloaded from the Internet or converted from music CDs. An MP3 player becomes the most suitable device for playing these files. Modern smartphones are mostly designed for using music apps and subscription services, while transferring and organizing MP3 files on your phone can turn out to be quite tricky. An MP3 player will let you effortlessly select music by artist, album or track title, or even release year. And don’t forget the super convenient playlist feature!
Perfect for active lifestyle
Keeping fit and leading an adventurous life are today’s biggest trends, and music is an essential component of active lifestyle. No matter what you’re into – running, going into the gym, hiking, cycling, or climbing – an MP3 player is a much lighter and smaller device than your mobile phone, which means it’s much more convenient to carry around. Plus, many MP3 players like the iPod Shuffle have special clips, so you don’t have to keep them in your pocket.
Save battery life
One of the biggest problems of smartphone users is the battery that dies in the middle of the day even when you’re not actively using the phone. Obviously, listening to music for hours has an even more drastic effect on the battery life. MP3 players, however, are known for lasting for days while playing music non-stop. That way you can take the pressure off your phone’s battery while enjoying your favorite tunes wherever you are without worrying about the battery life of your devices.
Mobile app to curb vandalism, power theft Launched in Nigeria
In a bid to curb the disturbing nuisances that stem from criminality in our society, Web Asset Limited, a Lagos-based technology company, has launched an interactive crime reporting system tagged ‘Hawk Eye’.
Hawk Eye is a mobile app that uses an innovative technology to checkmate crime in Nigeria.
The launch which took place in Abuja, was a beta launch piloted by Mr. Kayode Aladesuyi, chairman Web Asset Ltd., and developer of the Hawk Eye app.
The pilot launch was aimed at demonstrating how the app could be useful in finding a solution to the menace of utility and energy theft plaguing the electricity sector.
The demonstration highlighted the distinctive features of the app like the ability to select crime types, capture and send videos, images or text messages of the crime and direct these to appropriate security authorities for immediate action.
He added that the system offers a crime management platform with a robust command and control centre dashboard to display location of crime scenes and the nearest officers to respond to the reported crime.
The Hawk Eye system is the first national crime reporting system in the country and is one of the ways in which the public can lend its support to reinforce the governments’ unrelenting efforts in safeguarding lives and properties across the country.
Mr. Aladesuyi, explained that beyond reporting utility theft for the energy sector, the app had been developed with the potential to work with different security agencies and institutions in the country and deal with crime at all levels from kidnapping, vandalism, civil unrest, terrorism, extortion, etc.
He said: “We are always looking for better and more contemporary ways of safeguarding lives and private properties, including public utilities. The app which is a niche crime reporting app, will address the infrastructural gap in the area of emergency response system through internet-enabled mobile phones. The app also provides an alternative, fast and easy way of tackling security issues with exposure to lesser risks.”
“Hawk Eye enables officers in the field to receive dispatched incidents and option to file reports in real-time even while in remote locations. Through its unique offering of Global Announcement feature, the app allows communication with different communities on national emergencies, most wanted persons, among other emergencies. In addition, Hawk Eye provides a FindMe feature for users to notify Rapid Response units or family members in the event of kidnapping incidents,” he said.
Ernest Mupwaya, managing director of Abuja Electricity Distribution Company (AEDC), in his remarks said, “Energy theft is crippling the revenues of electricity distribution companies and impacting negatively on growth.” He explained that the distance and communication gaps were hindrances to checking criminal activities in the sector, adding that the app, as a security enabler would bridge these gaps.
