Why Wearables? Why now?

Cost of Processing reduced to 1/60x

Cost of Information Technologies (last 10 years)

Cost of Bandwidth reduced to 1/40x

Avg. cost sensor from$1,30 to $0,60 Wi-Fi becoming ubiquitous,

available free or at low costs

Increase of Connectivity

Smartphones personal Gateway to IoT

IPv6 allowing countless connections

Demand for Monitoring

Rising Health awareness

Mass Production

• Protective film against water and dirt for flat devices

• Thermoplastic foam for embedding, adhesion, sealing for 3D shapes

Customized to end-product and processing needs

2 functions : embedding and fixationLeveraging decades of professional woundcare

• Single vs. multi-day usechanging the fixation, leveraging breathable materials

• Acrylic adhesive in-line applied to patch(aggressive, not breathable, e.g. skin sensitivity of diabetes patients)

• Gentle adhesive solution- silicon (expensive, holes for breathability & extra layer)

- polyurethane

• Buy ready-made fixation/dressing rollsMake fixation from adhesive laminated films

Explanation of symbols: „+“ = „yes“, „-“ = „no“, „o“ = „can be“ or „depending on other parameters“.

Breathability for optimal fluid handling capacity

• Breathable TPU films enable longer use (less frequent change of patch)

• Hydrophilic membranes have a tight polymer structure, so water drops, dirt and microbes cannot penetrate
