Energy Harvesting
Introduction
About e-peas
e-peas semiconductor is a fabless semiconductor supplier and was founded in 2014. The e-peas product strategy is the Energy Harvesting, driven by the understanding that extremely-low power is a must-have for the realization of today’s and future industrial and IoT applications. One key aspect towards this goal is to extend the battery lifetime in such applications or even better make applications completely independent from any battery or wired power source.
After 10 years of research and filing patents for disruptive technologies, e-peas now offers a portfolio of energy harvesting devices including solutions to generate power from light, temperature, vibration and electromagnetic radiation.
With the very low cold start requirements and the very high converter efficiency the e-peas harvesting devices represent an industry leading solution. Beside the performance of the device itself the low number of necessary external components is an additional advantage to optimize the cost and board space which is often essential for small scale IoT use cases.

Photovoltaic Energy Harvesting
Let’s assume that you work with battery powered IoT wireless devices that operate under light sources that may come from sun, light bulb, tube, etc. You need to replace the batteries of those devices, because they run out of energy. This generates operational costs.
But, most probably, there is enough of energy in the light surrounding your devices that you could use to power them.
Depending on the lighting conditions (low light indoor conditions to bright sunny outdoor conditions), traditional photovoltaic (PV) cells can generate from 10µW to 10mW per cm².
When properly selected (material and topology) and sized (illuminated area), a PV cell combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient light.
Using e-peas’ photovoltaic energy harvesting, you will avoid typical operating costs associated with battery replacement.
WHAT EXACTLY DO WE OFFER?
Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries in any light conditions: bright, changing, or even in very low ones with a PV cell generating as low as 3µW.
e-peas offers you the following AEM [Ambient Energy Manager] reference:
- The AEM10941 allows you for harvesting energy from up to 7 cells in series solar panels producing from 3µW up to 625mW.
HOW DO WE DIFFER FROM COMPETITION?
Both references are 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

E-peas’ photovoltaic energy harvesting IC solution
AEM10941 – is the next generation integrated energy management subsystem that extracts DC power from up to 7 cells solar panels 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.
The AEM10941 harvests the available input current up to 125 mA. It integrates an ultra-low-power Boost converter to charge a storage element, such as a Li-Ion battery, a thin film battery or a super- or conventional capacitor. The Boost converter operates with input voltages in a range of 50 mV to 5V. With its unique cold-start circuit, it can start operating with empty storage elements at an input voltage as low as 380 mV and an input power of just 3 µW.
The low voltage supply typically drives a microcontroller at 1.8 V. The high voltage supply typically drives a radio transceiver at a configurable voltage. Both are driven by highly efficient LDO (Low Drop-Out) regulators for low noise and high stability.
Configuration pins determine various operating modes by setting predefined conditions for the energy storage element (overcharge or overdischarge), and by selecting the voltage of the high voltage supply. However, special modes can be obtained at the expense of a few configuration resistors.
The chip integrates all the active elements for powering a typical wireless sensor. With only seven external components, integration is maximum, footprint and BOM are minimum, optimizing the time-to-market and costs of WSN designs in all markets.
Five identical capacitors and two inductors are required, available respectively in the small 0402 and 0603 SMD formats.

RF Energy Harvesting
Let’s assume that you work with battery powered IoT wireless devices that operate within wireless waves rich environments. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.
But there might be enough of energy provided by the wireless emitters surrounding your devices that you could use to power them.
Those emitters include:
- GSM900 (BTx)925-960 MHz
- GSM1800 (BTx)1805-1880 MHz
- 3G (BTx)2110-2170 MHz
- WiFi2400-2500 MHz
And if not, you can equip the environment with dedicated emitters emitting power at 868MHz (Europe) or 915MHz (USA).
Depending on the power emitted by the source and the distance from the source (from 10’s of cm up to 15m), typical power levels you can harvest range from 10µW to mWs.
When properly selected and sized (frequency compatibility with available sources), an antenna and a balun (provided by e-peas for all above mentioned frequency ranges) combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient RF power.
Using e-peas’ RF energy harvesting, you will avoid typical operating costs associated with battery replacement.
WHAT EXACTLY DO WE OFFER?
Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries from received RF power levels as low as -19dBm.

Thermal Energy Harvesting
Let’s assume that you work with battery powered IoT wireless devices that operate in an environment presenting thermal gradients generated by heater, human body, furnace, motor, etc. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.
But, in some environments, there is enough of energy dissipated by surrounding machines that you could use to power your devices.
Depending on the available temperature gradients, TEGs can generate from 20µW to 10mW per cm².
When properly selected (material and topology) and sized (area exposed to temperature gradients), a TEG 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’ thermic energy harvesting, you will avoid typical operating costs associated with battery replacement.
