NAWA Technologies’ Ultracapacitors Growing Global Market for IoT Devices

NAWA Technologies’ next-generation ultracapacitors will revolutionise the growing global market for IoT devices, offering huge benefits in operational lifetime, cost, efficiency, safety and environmental impact.

NAWAAs the world becomes more connected, IoT devices can be found in billions of products. They play a crucial role in our daily lives, from bringing added convenience in domestic applications, like  wifi-enabled electrical appliances – such as smart meters – to improving the quality of our food by monitoring its condition during transportation. Constantly tracking factors like pressure, location, proximity, smoke, gas and light, IoT devices can be found everywhere from our homes to extreme environments including deep under the sea or at altitude in aerospace.

Thanks to this wide variety of applications and usage conditions, the number of IoT devices across the world is expected to grow exponentially, from 25 billion in 2020 to 80 billion before 2030*. This creates major challenges around performance, raising the question of how to power these devices – and to do so efficiently, cost-effectively and with minimal environmental impact.

Ronald De Graaf, Sales Manager for IoT at NAWA Technologies explains: “Many IoT devices spend most of their lives on stand-by, requiring a low amount of energy. But when the device needs to send a signal a short burst of energy is required. For example, in the oil and gas industry, when a transfer of pressure data is sent from a drill on the sea floor to a rig on the surface. If you then combine the long-term energy requirement with a remote location and extreme environment, an energy solution that is only based on a conventional battery is just too large and expensive. Our concept is the hybridization of our NAWACap ultracapacitors with conventional batteries, resulting in the perfect solution for these applications, reducing size and improving performance.”

IoT devices use many types of battery technologies, from non-rechargeable primary batteries such as regular AA or AAA alkaline to lithium primary cells to rechargeable lithium-ion batteries, but the need to provide repeated power bursts for transmission limits their lifetime, causing early failures or heat problems in the circuitry. Lithium is also a finite resource and has issues around recyclability and safety.

Greener solutions, such as energy harvesters – for example solar power, or systems that use kinetic energy or salt water to generate energy – can supply a sensor with low-level ‘standby’ energy but not the short bursts of energy required for data transfer.

NAWA Technologies’ NAWACap ultracapacitors are the solution. Based on carbon, they use a material that is abundant, recyclable and environmentally friendly. The NAWACaps can be packaged into small, flat cells and withstand extremes of temperature and the harshest environments, through deep sea to deep space. They also match ideally with the IoT sensor power use profile, coping with high current peaks, combined with long lifetime and therefore do not need to be replaced.

“Combining our NAWACap ultracapacitors with a lithium cell, creating a ‘hybrid’ battery, has many advantages. If we take a GPS tracking device as an example, often used to track valuable assets or integrated into the collar of a pet, the conventional approach is to use a non-rechargeable AA lithium battery, but this is very bulky,” continues Ronald De Graaf. “Integrate NAWACap and you could immediately reduce the reliance on lithium AA to AAA-sized batteries with superior performance, including the same or even an extended operational lifetime. One could also combine NAWACap with a coin cell resulting in an even flatter, lighter package with even better lifetime.”

Pascal Boulanger, Founder, Chairman of the board, CTO and COO added: “Our NAWACap system is the perfect companion solution for IoT devices. We can integrate our ultracapacitors with lithium rechargeable or non-rechargeable batteries like alkaline batteries, creating a system that is 80 per cent lighter and 60 per cent smaller, an overall reduction in volume and weight of more than 60 per cent.

“They are energy sources that can more than last the lifetime of a device – and, in fact, we believe we can double or even triple the lifetime of an IOT device, while greatly increasing the frequency of the data it can send in its life, making a step change in monitoring capability too.

In addition, they are able to operate under extreme conditions, making them an excellent solution for remote applications or in the cold supply chain, keeping food temperature efficiently monitored during transportation, substantially reducing losses and resulting in better quality food for us all.”

Ulrik Grape, CEO of NAWA Technologies adds: “As well as substantial savings through increased energy efficiency and maintenance-free systems, it is also important to consider the indirect environmental benefits. Our NAWACap technology requires only abundantly available, non-toxic, disposable and recyclable materials. As a result, NAWA’s technology provides and supports economical, environmentally friendly and safe solutions for the IoT market.”
