As the world pivots toward more sustainable and efficient solutions, the smart home and building industry is rapidly transforming as well. One of the most significant developments in this shift is the use of energy harvesting (EH) technology, which allows devices to be energy autonomous, eliminating the need for battery change and providing unprecedented added value.
At e-peas, we develop advanced energy harvesting PMICs that enable low power devices to run off harvested energy from solar and other environmental sources, removing the need for maintenance.
Why Energy Harvesting is Crucial for Smart Buildings
Traditional battery-powered devices in smart homes and buildings face a major limitation: battery replacement. In large-scale deployments like smart lighting, ambience monitoring, energy management, HVAC systems, or occupancy sensors across buildings, the cost and time required to replace batteries of a scattered network of sensor are immense not to say impossible. For example, in a typical large office building equipped with 5,000 sensors, if each battery needs to be replaced every two years, the labor costs, downtime, and waste management become significant. This is where energy harvesting steps in to provide a cleaner, cheaper, and more reliable alternative.
1. Lower Environmental Impact
Batteries, especially disposable ones, are harmful to the environment, contributing to landfill waste and potential soil contamination. By eliminating the need for batteries, e-peas’ energy harvesting solutions reduce e-waste and environmental hazards. Energy harvesting also helps reduce the carbon footprint by utilizing clean energy sources like ambient light, RF, thermal and vibration power.
2. Lower Total Cost of Ownership (TCO)
Switching to energy harvesting dramatically reduces maintenance costs. With e-peas’ EH PMICs, sensors and devices can operate for decades without any need for battery changes, cutting down on both material costs and labor. Additionally, there are no hidden operational costs associated with battery replacement logistics and disposal, further lowering the TCO over time.
3. Better Product Integration (with Long-Term Benefits)
Integrating e-peas PMICs into your devices requires a thoughtful redesign, especially when transitioning from traditional battery-powered systems. However, the effort is well worth it. By utilizing energy from solar PV cells, thermal, or vibrational sources, your products become more sustainable and cost-effective. The result is a highly competitive device that lowers long-term costs, reduces environmental impact, and leads in sustainable innovation. Furthermore, the absence of bulky batteries opens up new design possibilities, allowing for sleeker, lighter devices, and cleaner designs that enhance the product’s aesthetic appeal.
4. Higher Quality of Service (QoS)
Thanks to the “always-on” nature of energy harvesting, devices operating on energy harvesting can continuously operate without downtime. Traditional battery-powered devices experience performance drops as their batteries deplete. With energy harvesting, this issue disappears. Your systems remain consistently operational, ensuring that critical services, such as security or energy management, stay uninterrupted.
5. Reduced Preventive Maintenance
Energy harvesting significantly reduces the need for preventive maintenance. Since your devices are powered autonomously by harvested energy, they require minimal upkeep. This means your team can deploy thousands of sensors across the building and, quite literally, forget about them. With no more need to replace or recharge batteries, your smart systems operate efficiently for years, providing a hassle-free experience.
The Future is Here: Energy Harvesting in Action
Imagine outfitting your entire building with light-powered sensors and devices that need no battery changes for the next 20 years. With e-peas PMICs and partners’ energy storage solutions, this vision is not only possible but also cost-effective. The shift toward energy harvesting represents a significant upgrade for any smart home or building project, whether residential or commercial. By embracing energy harvesting, you are not only reducing environmental impact and operational costs but also enhancing the reliability and efficiency of your systems.
