Many consumers and industries developing IoT devices face the challenge of having to evaluate the pros and cons of either using batteries or to plug-in their devices for power. Although batteries are much more convenient choice than plug-in charging, batteries can pose issues of time and cost when they need replacing in the field; this is where Energy Harvesting technologies are an effective solution.
Energy harvesting used in IoT devices means that devices can be recharged by ambient sources that surround them. e-peas Ambient Energy Manager (AEM) PMIC Family is an integrated energy management circuit that extracts DC or AC power from different types of ambient energy harvesters to simultaneously store energy in a rechargeable element and supply your system with two independent regulated voltages.
Ambient energy sources:
Photovoltaic (Indoor and Outdoor Sources)
Vibration (Constant Frequency Mechanical)
Radio Frequency (Very Low Power)
What you will learn
How Energy Harvesting can potentially remove batteries from designs
Reduce expensive field maintenance
Give batteries longer life
Help reduce global waste
The design of greener products; UK designers can access the inovate fund
The demand for IoT devices that does not require battery replacement or plug-in recharging is increasing; battery replacement or plug-in recharging simply costs time and money. The solution ‘Energy Harvesting’ is becoming more popular – this is the recharging of IoT devices wirelessly by its surrounding ambient sources.
The main benefits of Energy Harvesting include:
Reducing battery replacement cost
Reducing the storage element size
Allowing additional features
Energy Harvesting is setting new standards for the industry as the number of companies shifting their devices to this breakthrough technology is growing. E-peas’ Ambient Energy Managers (AEM family) are suitable for Industrial, Smart Argriculture, e-Health, Security, Society and Wearables, Home Automation, Retail, and Mobility Applications.
e-peas has teamed up with SODAQ for a webinar to show potential customers how Photovoltaic Energy Harvesting can be implemented in Animal Tracking Tag Cases in Smart Agriculture.
What will the webinar cover?
Principle of evaluating the energy balance before design implementation
SODAQ’s approach to achieving low-power consumption on IoT edge devices and how these concepts came into play in developing the “mOOvement” Cattle Tracker. SODAQ’s low-power philosophy synergized with the e-peas AEM10941 lead to a fully autonomous cattle tracking solution that delivers real-time location data to free-range cattle farmers.
The webinar was held on Thursday 26th November 2020 at 10:00 GMT/11:00 CET.
The AEM is an integrated energy management circuit that extracts DC or AC power from different types of ambient energy harvesters to simultaneously store energy in a rechargeable element and supply your system with two independent regulated voltages. The AEM family enables you to extend the battery lifetime and ultimately eliminates the primary energy storage element in a large range of wireless applications such as industrial monitoring, geolocation, home automation, tracking and wireless sensor nodes.
