OptiJoule™ smarter energy harvesting PMICs

The simplest, most effective, and most economical way to cut battery dependency in wireless IoT applications.

OptiJoule™ EH PMICs don’t need interface components, whichever type of harvester you connect to them, and they autonomously adapt to light, thermal gradient or vibration harvesters.


OptiJoule™ EH PMICs work with up to four inputs, each of which adapts independently and autonomously to the type of harvester
connected to it.


Simplicity of design cuts costs. What’s more, you only need stock one PMIC for multiple applications and one product will be ready to use with a variety of energy harvesters, or any combination of them.

Towards a battery-free, self-sustaining IoT

With billions of sensors being installed into IoT networks around the globe every year, many of them beyond the reach of power grids, batteries are being deployed at an alarming rate. It’s alarming because most of them contain poisonous chemicals, most commonly lithium, posing a contamination threat of enormous proportions.

What’s more, the cost of changing batteries in remote locations can be prohibitively expensive, so there’s a strong economic case for eliminating them too, making edge IoT sensor nodes self-sustaining.

Enabled by effective
power management
of harvested energy

Even where elimination isn’t possible, the effective use of energy harvesting can dramatically reduce the number of batteries that may be needed to run a sensor over its operating life.

The challenge has been to develop a viable technology for cost-effective management of harvested energy in the microwatts to milliwatts range needed to power remote sensors. OptiJoule™ EH PMICs meet that challenge.
