Batteryless and Selfpowered Electronics

Batteryless and Selfpowered Electronics

Let us help you remove batteries and power cables from you electronic product.

We help companies assess the feasibility of energy harvesting and build batteryless prototypes with energy optimized power management design. In high volume cases, we offer power management ASICs to realise optimum power consumption and low cost in low power devices, especially in IoT and wearable wireless sensor applications.

Further we offer a broad range of test facilities and climate chambers to characterise new energy harvesting technologies, with deep knowledge in how both solar, thermal, kinetic and RF energy harvesting technologies perform in real life.

What is Batteryless and Selfpowered Electronics?


Batteryless device in 8 steps


Our 8 step process helps you challenge and re-discover current markets and customers. We aim to help you break away from incremental innovation and throughout the 8 steps, IdemoLab will focus on helping you create new, meaningful and valuable products for your customers and your business.

Step1

The Energy Potential

We map out the current device energy consumption, as well as an assessment of the energy potential in the environment. Further the current practical installation and maintenance process, is studied to reveal practical barriers.

Step2

State of the Art

Relevant energy harvesting technology deep-dive with state-of-the-art investigation and reviewing of existing competitor solutions.

Step3

Initial Concepts

We begin to form multiple initial self-powered concepts into physical mock-ups with our customer. After an evaluation process we move forward with 2 concepts.

Step4

Self-powered Concepts in Context

Where does your product get installed? How does it fit into your user’s routines? During this step, we bring the concepts into the scenario they have been designed for, where they are tested by users.

Step5

Technical Validation and Certification

Before venturing into costly requirement specifications and product development, this step will provide valuable early design input, uncover technological, mechanical and certification challenges as defined by DELTA’s experts in reliability testing and CE Marking.

Step6

Energy Harvesting Component Sourcing

Producing batteryless devices requires reliable components but also reliable sourcing in a new market where comprised of many young & small suppliers. In this step the sourcing options and challenges are addressed together with DELTA’s partners.

Step7

Prototyping

Functional self-powered hardware proof-of-concepts are build by IdemoLab’s engineers using insights and data from the preceding steps. We aim at developing proof-of-concepts focusing on the primary function, demonstrating the most interesting aspect of the concept developed.

Step8

Development and Production Plan

A plan for next step activities is made, such as requirement specification, design for manufacturing, industrial design, lead times, certifications, and access to market.

The barriers for companies to get their products batteryless


icon_unknown-energy

Unknown batteryless potential

It is hard to evaluate exactly how much ambient energy there is in the vicinity of a product from changing light conditions, heat differences and movements and thus hard to evaluate the potential of realizing batteryless device powered by energy harvesting.

Solution: IdemoLab 8 step process

DELTAs energy logger can be placed in the product environment and log light levels, temperature gradients, movements and vibration levels and RF signal strengths. Combined with an analysis of the power usage of your products, the energy potential is evaluated.

Ultra low power and low cost components

A primary driver for the succes of a selfpowered device is the power management of the sparse energy generated from the energy harvester. Standard off the shelf power management IC’s on the market are often limited in their specifications meanwhile having a high cost.

Solution: DELTA ASIC

Efficient use of the sparse amounts of energy present from the ambient environment, can be realised through Application Specific Integrated Circuits (ASIC) with specialised energy harvesting interfaces ensuring efficient impedance matching meanwhile leakage currents are minimum.

Characterisation and reliability of batteryless solutions

The reliability and lifetime of self-powered technologies compared to using a battery can be complex. From changing external environments due to use, day/night, seasons, geography, installation procedures etc is difficult to evaluate the expected lifetime of a energy harvesting powered device.

Solution: Highly Accelerated Testing

DELTA has long experience with testing and certifying reliable electronics in our broad range of test facilities and climate chambers. We are able to physically simulate almost any environment the selfpowered device would be exposed to and identify any week point in the batteryless design, before it fails in the market.

What our customers say about us


mark-seidenfaden_250x250px

Teaming up with IdemoLab, opened up a new world of connected and self-powered applications to the team of Seidenfaden Design. The collaboration was professional and fun. The combination of a hands-on approach, using functional mock-up models, together with the strong, technical knowledge of the IdemoLab team, meant that the focus was always on the practical implication, it’s feasibility and thus the experience of the end user.

What kind of harvesters can power what?


Thermal Energy

Thermal Energy

Harvesting energy from temperature gradients. On a warm radiator the wirelessly controlled thermostat can be self-powered, needing zero maintenance.

Kinetic Energy

Kinetic Energy

Piezoelectric material can harvest energy from vibrations on motors or structures like windmill blades, enabling self-powered wireless sensors for structural and machine health monitoring.

RF Energy

RF Energy

Specially designed antennas can harvest RF energy from existing or actively induced wireless signals powering low power wireless sensors implemented into structures like concrete for monitoring of bridges.
