Top 10 emerging technologies to watch in 2021

According to The World Economic Forum’s annual list of breakthrough technologies, this year’s list has the most significant potential to impact the world positively. From climate change to public health, technology will play a critical role in finding solutions to many of the world’s challenges. This year’s emerging technologies demonstrate the rapid pace of human innovation and offer a glimpse into what a more sustainable, healthier future could look like.

“Our goal with the list is always to identify those with the greatest potential for impact, but we also want to provide a diverse and inspirational list,” said Jeremy Jurgen, Managing Director at the World Economic Forum. “Every single technology has the potential to solve major global challenges.”

Decarbonization technologies

As nations race to deliver on their commitments to tackle climate change, a multitude of technologies that offer lower-carbon footprint solutions, or suck carbon dioxide out of the air, will need to scale up fast. These technologies will include net-zero emissions air-conditioning, low-carbon cement, renewable energy sources and meat-free protein, among others.

Self-fertilizing crops

Providing food for the world’s growing population relies heavily on such nitrogen-containing industrial fertilizers as ammonia – the production of which accounts for 1% to 2% of global carbon dioxide emissions. New engineering approaches enable crop plants to produce their own fertilizer by mimicking a symbiotic relationship between plant roots and soil bacteria that occurs in nature.

Disease-diagnosing breath sensors

Human breath contains more than 800 compounds. New breath-sensing technologies analyze these compounds and detect changes in concentrations of compounds associated with diseases. Early-stage testing has demonstrated the potential of breath sensing technologies to diagnose COVID-19, tuberculosis and cancer.

On-demand drug manufacturing

Traditionally, drugs are made in large batches through a multi-step process with different parts dispersed among many locations worldwide. Recent advances in microfluidics and on-demand drug manufacturing open the possibility of common drugs like antidepressants and antihistamines being made to the exact dose and formulation tailored for an individual, on-site at their local pharmacy.

Energy from wireless signals

Devices that do not require much power to operate, such as pacemakers and smartwatches, could soon be wirelessly charged through Wi-Fi and 5G signals, leading to a future where low-power wireless devices never need plugging in.

Engineering better ageing

Research that unlocks the understanding of ageing mechanisms enables the development of targeted therapies that could one day stave off dementia and other age-related ailments, leading to healthier elderly years.

Green ammonia

Green ammonia, which is made from cleaner sources of hydrogen, could provide more environmentally friendly fertilizers for crops.

Wireless biomarker devices

Monitoring chronic diseases such as diabetes and cancer requires frequent blood testing to identify and track certain biological markers. Innovations in wireless, portable and wearable sensors integrated in clothing or contact lenses could soon monitor this vital information continuously.

Houses printed from locally sourced materials

Building houses with 3D printers could help tackle the challenge of inadequate housing for 1.6 billion people worldwide. The concept of 3D printing houses has been around for a while, but new advances enable houses to be built from locally sourced materials like clay, saving time, money and energy on transporting building materials to the site.

Space internet of things

At least 10 billion active devices make up the internet of things (IoT), a number that is expected to more than double in the next 10 years. Maximizing IoT benefits in communication and automation requires devices to be spread worldwide, but cellular networks span less than half the globe, leaving enormous gaps in connectivity. A space-based IoT system could patch those gaps, using a network of low-cost, low-weight nanosatellites that orbit a few hundred kilometers from Earth.
