    Top 10 Greatest African Inventions

    The African continent is home to a plethora of incredible inventions that the rest of the world isn’t aware of. Here are some of the most amazing and proudly African inventions. So, without further ado, here are the Top 10 African Inventions.

    10. Mathematics– Egypt

    The origins of mathematics can be traced back to African prehistory. The Lebombo bone, discovered in Swaziland’s Lebombo Mountains and dated to around 35,000 B.C., is the oldest known possibly mathematical object. Many of the math concepts taught in schools today were developed in Africa. Over 35,000 years ago, Ancient Egyptians wrote math textbooks that included fraction division and multiplication as well as geometric formulas for calculating the area and volume of shapes.

     9. CAT Scan Machine-South Africa

    The CAT scan is an incredible African invention that is widely used in the medical field globally. Allan Cormack, a South African, invented this technology. The concept, however, was developed and commercialized in the United Kingdom. In 1979, the inventor received the Nobel Peace Prize for his invention. The CAT scan, electronic detectors, and X-ray sources are rotated around the body, providing the radiologist with a precise map of the body’s cross-section (tissue slices).

    8. Cybertracker-South Africa

    The cyber tracker is an amazing innovation that has its roots in philanthropy as well. After spending time with the San, Louis Liebenberg felt compelled to use technology to assist traditional hunter-gatherers in preserving their knowledge and innate tracking abilities. Trackers can now work in ecotourism, as rangers in anti-poaching units, wildlife monitoring, and scientific research thanks to the development of Cybertracker software. The software features an icon-based user interface that allows non-literate trackers to record complex geo-referencing and animal behavior observations. The invention has become a cornerstone in
    the creation of jobs for indigenous African communities, and is critical in anti-poaching and conservation efforts globally.

    7. Cardiopad-Cameroon

    Another amazing invention of African technology is the Cardiopad which was invented by a Cameroonian entrepreneur called Marc Arthur the very first touch screen medical tablet was invented and made in Africa. It is a computer tablet that is used for heart examinations. The gadget allows such examinations as electrocardiograms to be conducted in rural and inaccessible locations. With the Cardiopad, electrodes are placed on the patient and connected to the model that, in turn, connects to the tablet. When a medical examination is performed on patients in a remote village, for example, the results are transmitted from the nurse’s tablet to that of the doctor who then interprets them. The gadget is mostly used in areas where very urgent diagnostic tests need to be carried out but are inaccessible.

     6. Quiet Cellular Antenna Technology-South Africa

     This is one of the most intriguing African inventions.Gordon Mayhew-Ridgers and Paul van Jaarsveld created cellular antenna technology which significantly reduces noise emissions from cellular stations while employed as principal engineers at Vodacom. This African Technology is based on one phased-array principle that blocks radio frequency transmissions along a given direction and also provides Omni-directional coverage. The antenna has been tested in other parts of the world and has worked extremely well. Trail measurements have shown the radio signal frequency levels can be significantly reduced while at the same time maintaining the original GSM coverage. The SKA is projected to be 50 to 100 times more sensitive than other radio telescopes ever built, and an area without much radio emissions is essential for the success of the project.

    5. Charging Shoes-Kenya

    We’ve had smartphones for a while now, but why not take the next step and have smart shoes to go along with them? That is exactly what is going on in the world of technology right now. ANTHONY MUTUA, 24, of Kenya, created an ultra-thin crystal chip that can charge mobile phones when placed in shoe soles.

    Once installed in a regular shoe, the chip generates electricity when you step on it, which can be harvested in one of two ways. You can charge your phone while walking or running using a thin extension cable that runs from your shoe to your pocket, or you can store the electric energy and charge your phone after you have stopped walking or running and removed your shoes.

    4. Sproxil system: A fresh way to fight counterfeit drugs– Ghana

    Many thoughts cross your mind as you stand in front of a shop shelf, looking at the various products on display. You may be wondering if the label on a particular product is genuine.

    Ghanaian Ashifi Gogo invented a text message verification process to thwart the distributors of counterfeit drugs in developing states

    The Sproxil system makes use of the most basic mobile phone technology and takes advantage of the fact that SMS messaging is available on almost all phones. It employs a system that allows the consumer to text a number revealed by scratching the panel on a box of medication to verify whether or not the medication is genuine. The consumer does not need to download a special app, and the SMS text is free, paid for by Sproxil, who then makes money from the large pharmaceutical manufacturers and distributors who benefit when people buy legitimate products rather than illegal counterparts. “It’s like a drug 999 call,” Gogo says.

    3. The Hippo Roller: A water collection solution-South Africa

    Water is often carried in 20-liter (5-gallon) buckets balanced on top of heads when water supply points are as far as 10 kilometres (6 miles) from home. The Hippo Roller is a simple solution that allows water collectors to collect up to five times more water.

    The Hippo Roller is a 90-litre (24-gallon) container that rolls across the ground. Water collectors are typically elders, women, and children. Rather than being carried on the head, the water is rolled–either pushed or pulled. This increases access to water, which improves food security and income generation.

    The Hippo Roller was invented in 1991 by two South Africans, Pettie Petzer and Johan Jonker. They were both aware of the effects of the water crisis on daily life. The Hippo Roller Project was founded in 1994 with the goal of “assisting communities in improving access to water–90 litres at a time.”

    2. Carbon Steel-Tanzania by Haya people

    Western scientists and historians have long used evidence from European archaeology to explain the iron bloomery process. Ethnographic, technological, and archaeological research into the technological life of the Haya of northwestern Tanzania reveals that these people and their forefathers 1500 to 2000 years ago practised a highly advanced iron smelting technology based on preheating principles, producing carbon steel as a result.

    This sophisticated technology may have evolved as a result of overexploitation of forest resources. These discoveries have historical significance for both Africa and metallurgy.

    ‘Carbon steel’ is a type of steel with a 0.05-2.1 percent carbon content by weight.

    ‘High carbon steel is used to manufacture milling machines, cutting tools – such as chisels – and high strength wires.

    1. Medicine-Egypt

    Vaccination, autopsy, trepanning, brain surgery, and skin grafting were all performed in ancient Africa before they were ever performed in Europe.

     The earliest known surgery was performed in Egypt around 2750 B.C. Medical procedures performed in ancient Africa before they were performed in Europe include vaccination, autopsy, limb traction and broken bone setting, bullet removal, brain surgery, skin grafting, filling of dental cavities, installation of false teeth, what is now known as Caesarean sections, anesthesia and tissue cauterization.

    Ancient Africans were able to perform amputations, and they were also able to prevent infection by soaking wounds in wine.
