CPI demonstrates the feasibility of novel Battery-on-Circuit technology for smart labels

CPI, an independent technology innovation centre and founding member of the High Value Manufacturing Catapult, today announced the successful completion of POETICS, a collaborative project aiming to develop low-cost Battery-on-Circuit technology for printed smart labels used to track assets. The outcomes of this project could help lower production costs and drive industrial growth within the printed electronics industry.

Asset tracking solutions help companies manage inventory and keep track of shipping, to prevent items from becoming lost or damaged in transit, which can result in significant costs. Compared to existing asset tracking solutions with complex installation procedures, the smart labels by London-based SME Reelables are much quicker and easier to use. Reelables’ smart labels, which attach to objects like a sticker and can be tracked with a phone app, could ultimately help companies save time and money. However, in order to enable the smart labels to be mass-produced at an ultra-low cost, an inexpensive battery to power the smart labels needed to be developed.

In collaboration with Reelables, CPI led a 12-month feasibility study with £100,500 of funding from Innovate UK to develop a low-cost battery that would be formed onto each smart label’s circuit. This Battery-on-Circuit solution, designed with expertise from project partners Cisco and Digital Catapult, is more affordable than other options currently available for printed electronics. It also eliminates the need to power the smart labels with a bulky external battery while strengthening the smart labels’ functionality and marketability.

CPI provided crucial support from its electronics and formulation business units to aid in the development of a public demonstrator prototype for real-world testing. The services that have been provided include thermal evaporation of lithium metal anode coating, electrolyte formulation, cathodic slurry formulations and coatings, battery pouch cell device assembly and battery cell testing. Additionally, CPI compiled a written report detailing how the technology will be manufactured at larger scales and the potential it could bring to the printed electronics market.

Duncan Lindsey, Business Development Manager at CPI, said: “The successful outcome of this project enables Reelables’ smart labels to have the right compact form factor for the asset tracking application, while achieving a longer lifespan at a low cost. We look forward to how our novel battery will enhance other printed Internet of Things (IoT) devices across a variety of industries.”

Brian Krejcarek, CEO at Reelables, said: “We are delighted to have successfully developed an affordable, integrated and flexible battery for our smart labels with CPI’s facilities and expertise. This new technology could boost the market value of our products and allow more companies to benefit from them.”

Access to quality facilities was one of the main drivers for deciding to locate the business at the NETPark. We have been able to use this as a launch pad to link into support from CPI and world-class expertise from Durham University.

Steve Clements, - Managing Director, aXenic

CPI has developed a specialist offering to support SMEs looking to develop their printable electronics applications and our partnership with Business Durham has been instrumental in attracting several SMEs to locate here in the region.

Dr Jon Helliwell, - Director of Printable Electronics, CPI

The proximity to the universities and the infrastructure are very important factors. Ultimately having a presence in Europe is very valuable to us and we intend to stay at NETPark for many years to come.

Dr Arnab Basu, - CEO, Kromek

We initially came because of the printable electronics centre but access to a highly skilled semi conductor workforce in the North East has been a key factor in us staying and growing here, as well as the value for money office space and the access to funding.

Ken Williamson, - COO, PragmatIC Printing

The quality of the facilities at NETPark and the attitude of staff is first class. It has a really dynamic, innovative atmosphere.

Dr Neil Loxley, - Chief executive, IBEX

It fits perfectly for us that we’re surrounded by like-minded companies at NETPark. There are a number of highly skilled people in the area who can help us grow our business. The facilities and services offered by NETPark are first class, they make office life simple and engaging.
