Shown here is a leakage sensor for ostomy applications,
developed together with Witte Technology GmbH
and Lohmann GmbH & Co. KG.
tro's Platilon® enable the next generation
of printed electronics for healthcare
devices. These films are skin-friendly,
soft, matte, stretchable, printable, and
breathable.
The newest grades of Platilon are
explicitly designed for high printing
quality, processability, and mechanical
strength. These multilayer films facilitate
easier printing, curing, and converting
processes for printed electronics.
Collaborative Approach for
Customized Films
As a material supplier, Covestro collaborates
with suppliers and printing
partners across the value chain to develop
a customized film that meets specific
product requirements while shortening
device manufacturers' time to market.
Smart Devices, Medical Wearables,
and Flexible Electronics. For instance,
Covestro collaborated with Henkel to
produce samples utilizing Platilon TPU
film on a stiffer polypropylene carrier,
enhancing processability with Henkel
LOCITE ECI 1014, a highly conductive
silver ink, which dries at temperatures
as low as 80 °C. Printability with silverbased
inks is important because it ensures
good conductivity and reliable
sensor integration.
" Henkel and Covestro have a long history
of working together to find customized
solutions for our customers, " says Pia

Technologies. " This sample showcases
superior printing quality and fine-line
printing, suitable for smart devices, medical
wearables, and flexible electronics. "
Innovative Smart Patch Detects Bag
Leaks for Enhanced Patient Comfort.
Working in collaboration with Witte
Technology GmbH and Lohmann
GmbH & Co. KG, Covestro film materials
contributed to developing a smart
patch for early detection of ostomy bag
leaks. People with artificial intestinal outlet
(stoma) use ostomy bags, which collect
the gut and bowel liquid. These bags
can sometimes leak, which can be associated
with discomfort for the patient.

The patch is designed for retrofitting an
ostomy bag and can be integrated into
existing solutions.
" The excellent collaboration among
Witte Technology, Lohmann, and Covestro
has yielded a groundbreaking solution "
says Dr. Volker Lutz, head of new
business development, Lohmann GmbH
& Co. KG. " With its innovative sensor array
on medical-grade Platilon TPU film,
this smart patch promises enhanced
comfort and peace of mind for ostomy
patients worldwide. "
Cutting-Edge Smart Bio-Sensing Patch.
" The future of printed wearables belongs
to pioneering patches aimed at better patient
comfort and enhanced accuracy, "
