BEWELL LinkedIn post – On the challenges in the transformation of the powerful, conventional electronics stack into “stretchy electronics”.

by

In response to The Future of Electronics is Stretchy by Printed Electronics World.

Yes, we agree with that and try our best in the BEWELL project to achieve this. But the challenges are quite significant to transform a powerful, conventional electronics stack into “stretchy electronics”.

BEWELL LinkedIn post – On LOPEC conference

by

The LOPEC conference for printed electronics featured our presence during the business conference part, in which we will present “Opportunities and challenges of printed electronics” from the perspective of a jewelry manufacturer.

“Even Austrian jewelry manufacturer Swarovski adds functionality to their crystals through printed electronics.” During the presentation we will showcase how we do this for wearable electronics in the Horizon project “BEWELL”.

Technology demonstrations

by

An early technology demonstration was shown in the Prinse 20 seminar end of January at VTT in Oulu Finland. There the Imec Museic evaluation board was connected with printed electrodes in the targeted patch form factor to measure ECG in wrist. The result is shown in Figure 1.

Figure 1: ECG sensing demonstration using printed electrodes and the Imec Museic evaluation board.

The next version of technology demonstrations for skin patches will utilize several functional layers integrated as a vertical stack structure as schematically illustrated in Figure 2.

Vias on stretchable substrate

Printing multi-layered electronics on stretchable or flexible substrates needs a solution to fabricate electrically conducting vias from one layer to another through the substrates. VTT has developed a reliable via printing process on stretchable TPU substrate. Scientific manuscript is under preparation.

Charging of printed Lithium-Ion-Battery by perovskite solar cell

by

In order to create fully independent product without need for any external charger and external connectors, the battery is connected with a state-of-the-art perovskite module which has enough output voltage for charging the battery outside and also at indoor light conditions. The perovskite module is built onto flexible PET substrate and has round shape in order to be compatible for integrated with all other elements of the final product. In picture below, the processing steps, top and cross-section views and electrical performance are demonstrated of flexible PSC module created for BEWELL project at IMEC.
