There would be 274 million battery replacements a day in a 10-year lifespan scenario and the number would be 913 million per day in case of three-year lifespan
PsiKick, Inc., a venture-backed startup developing ultra-low power wireless sensing systems, released an infographic on the shrinking expectation of internet of things (IoT), that revealed the expectations for number of IoT devices is falling due to the continued dependence on batteries to power these devices.
The start-up highlighted the huge decline in the number of IoT devices estimates by leading research and technology firms. It mentioned the prediction by IBM of one trillion IoT connected devices by 2015, then the revised forecast by Cisco of 50 billion devices by 2020. Most recently, GSMA has predicted a mere 25 billion IoT connected devices by 2025.
Consequences of battery replacement
The infographic highlighted the consequences of replacing battery in a trillion-sensor market by considering the scenario of achieving the battery lifespans of 10-year and in a more realistic case of 3-year average lifespan of battery. The numbers found out are overwhelming. There would be 274 million battery replacements a day in a 10-year lifespan scenario and the number would be 913 million per day in case of three-year lifespan.
Commenting on the findings, Brian Alessi, Director – Product Marketing, PsiKick, said, “Exploring the battery problem in a trillion-sensor world is overwhelming, but even putting it into the perspective of an industrial environment with just 10,000 sensors, that’s still nearly 3,333 battery replacements each year. In many cases, the additional labor cost alone of monitoring and replacing batteries begins to eclipse the benefits of the wireless sensors themselves.”
Bob Nunn, CEO of PsiKick, said, “Customers are excited to deploy IoT sensors to solve a problem until they realise it creates another one – battery replacements. We believe the battery to be a major contributing factor to why IoT device predictions have not been met. Sensors that power themselves entirely by harvested energy, are a game-changer that enable businesses to truly harness the power of the IoT, while saving time and money that would have been wasted on batteries.”
The infographic highlighted reasons regarding the obstacles created by batteries in cost effective implementation of Industrial IoT. These include finite lifespans of batteries that could cause gaps in mission critical data, battery-powered IoT sensors require manual inspections, battery’s physical dimension can limit sensor functionality and batteries can cause safety risks.
