Currently, IoT devices are much more battery-powered and at 3 times more expensive than the one chip, they supply. Nevertheless, standard IoT devices are unable to perform without a battery, and small batteries are fully discharged more often. Therefore, battery miniaturization leads to the high intermittent of IoT devices, as they stop operating whenever the battery is exhausted. Therefore, scientists managed to create an innovational microchip, which is called BATLESS, that can continue to perform in the case when the battery is fully discharged.
The newest development was made by the group of scientists, led by Associate Professor Massimo Alioto, form the National University of Singapore.
The Internet of Things (IoT) has a huge impact on various industries and help to form our daily lives in significant ways. IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS), microservices, and the internet. It can be applied in various fields and it can be used by different people such as used by a person with a heart monitor implant or a car that has built-in sensors to alert the driver when tire pressure is low. One of the significant issues of IoT devices is the inability to long-continued perform under strictly limited energy sources, therefore, it requires high power efficiency. IoT devices usually applied in the massive scale and in places, which are distant and hard to service often. Battery-indifferent sensor nodes require continuous operation in spite of the intermittently available battery energy and hence require the low peak-power operation to fit the fluctuating power made available by the harvester when the battery is out of energy. Consequently, the self-abundance is the crucial moment for IoT' appropriate operating.
BATLESS is produced using newest power management technology that provides the capacity to self-start and pursue to perform under dull light without any battery support, using a tiny on-chip solar cell. Furthermore, this technology significantly decreases the size of the batteries needed to power the IoT sensor nodes, which makes them 10 times tiny and cheaper to manufacture. Assist. Prof. Alioto mentioned that batteries, which are used for IoT devices can be shrunk fundamentally, as they are not required for continuous supporting. Therefore, this innovational technology could enable smaller and cheaper Internet of Things (IoT) devices.
