Page 8: Introduction And Features
D5.4: Multi-sensor system integrated into wearable fabrics 8/42 1 Introduction and features 1.1 Executive summary This document accompanies the actual / “physical” prototypes of the MOBISERV Wearable Health Supporting Unit (WHSU) (shirt and band for daily use, pyjamas for night use, together with a data logger and an application on PC).
Page 9: Structure Of The Document
D5.4: Multi-sensor system integrated into wearable fabrics 9/42 Figure 2: Direct connection with secondary user 1.3 Structure of the document This document is organized as follows. The first chapter provides a general overview of the system and possible configurations. The second chapter is dedicated to the description of the daily and nightly application and the garment that is used in each case.
Page 10: Garments
D5.4: Multi-sensor system integrated into wearable fabrics 10/42 2 Garments Within the scope of MOBISERV two different types of garments have been created for vital signs monitoring: the first one refers to sensorized shirt and band for day use, and the second one to nightgown for night use.

D5.4: Multi-sensor system integrated into wearable fabrics 12/42 Figure 4: The visual label with instructions for the correct use of shirts A very simple label assists the user by means of four basic steps, during the use of the WSHU. The final prototypes of shirts for female and male are illustrated in Figure 5 and Figure 6.

D5.4: Multi-sensor system integrated into wearable fabrics 13/42 Figure 6: The four textile electrodes in the inner side of the female shirt The day garments collection also includes a band that can be used during a short time window, for instance just to monitor an exercises session during the day. The band could help to overcome possible lacks in acceptability by the users that do not want to wear the sensorized shirt for the whole day.
Page 14: Night Garments
D5.4: Multi-sensor system integrated into wearable fabrics 14/42 2.3 Night Garments As for the day garments also night monitoring system has been completely redesigned to include all recommendations made by the users and by the experts within the evaluation trials. In particular, the idea to have a pyjama has been abandoned and replaced by a nightgown that seems to be easier worn and more accepted by elderly in general.
Page 15: Figure 9 The Label Inserted In The Nightgown
D5.4: Multi-sensor system integrated into wearable fabrics 15/42 The label for nightgown also contains the instructions to correctly use the ANT data logger for temperature monitoring, as shown in figure 7. Figure 9 The label inserted in the nightgown Two textile electrodes are available as conductive cuffs (see Figure 10). An elastic material together with a cord lock system has been inserted in order to let the user adjust and optimize the skin/electrode contact without losing comfort.
Page 16: Figure 11 Female Version Of The Nightgown
D5.4: Multi-sensor system integrated into wearable fabrics 16/42 A specific ANT module has been designed to interface properly the sensors as explained in chapter 3. Nightgown presents: a) Two textile electrodes placed on the cuffs that can be used to detect ECG and are adjustable by means of elastic ribs.
