The Vibration Solution

When would a Vibration Energy Harvesting solution be right for you?

Let’s assume that you work with battery powered IoT wireless devices that takes advantage of vibrations from ambient environment to acquire necessary energy. Without energy harvesting, chances are you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

In fact, in some environments, there is enough of energy dissipated by surrounding machines that you could use to power your devices.

When properly selected (material and topology) and sized (area exposed to temperature gradients), a piezoelectric harvester combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from hot or cold sources.

Using e-peas’ piezoelectric energy harvesting, you will avoid typical operating costs associated with battery replacement.

What exactly does e-peas offer?

Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries from any temperature gradients.

e-peas offers you 1 AEM [Ambient Energy Manager] reference:

• The AEM30940 allows you for harvesting energy from a vibration energy harvester

Why e-peas? How does e-peas differ from competitors?

This reference is based on e-peas unique AEM platform offering:

• top energy conversion efficiency
• the fastest supercapacitor charge
• the lowest cold-start power
• the smallest footprint and associated components BOM

In addition, you will get direct access to engineering support by our designers.

Use Cases

Smart Shoes

With increasing popularity of the concept of the Internet of Things, or IoT, smart home or wearable device products are no longer a new thing. The next big thing will revolve around the need of the fashion industry: smart clothing, smart eyewear and smart footwear.

A smart shoe, by its nomenclature, is a shoe embedding sensors, tracking different kinds of data from the human body: how fast you walk, how heavy each step you move, the position where you exert your power and its distribution, etc. These features are not only critical for training athletes to keep track of their performance, they could also bring tremendous benefits to ordinary shoppers. Your health conditions can now be honestly recorded and presented to medical institute for accurate analysis to prevent diseases. These critical readings, under wearers’ permission, can also be compared with data on the cloud for caregiving institutes or insurance providers to offer a tailored package for each individual clients.

A smart shoes can also intelligently accommodate each wearer’s walking or jogging habits or where they live to make adjustments. More and more global athletic & lifestyle brands have also launched similar smart products to incorporate not only smart shoes but also smart wristband, smart watches, etc. Big data can all be connected to provide a comprehensive overview of your physical wellbeing. Users can also track his or her own fitness and workout progress more easily.

E-peas Solutions

E-peas is compatible with piezoelectric energy harvesting solutions, where a piezo pad can be embedded at the bottom of a shoe which automatically transform each steps from the walker into endless power. Take a look at the “AEM30940 for Vibration Harvesting” section below for more details.

AEM30940 for Vibration Harvesting

E-peas’ vibration energy harvesting IC solution – AEM30940 – is an integrated energy management subsystem that extracts DC power from a piezo or micro turbine generator to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the primary energy storage element in a large range of wireless applications like industrial monitoring, home automation, wearables.
