Demonstration of large-area capability of printed electronics involving complex device architecture: an all-printed multi-modal sensing mat that can monitor and communicate vital signs as well as posture details of a person that is lying on it. The sensing mat consists of a combination of printed piezo-resistive and piezo-electric sensors, which enable measurement of vital signs and posture. These sensors are in the form of large arrays, enabling highly granular measurements.
The sensing mat consists of a combination of printed piezo-resistive and piezo-electric sensors and can be placed under a bed sheet, enabling long-term monitoring of babies in a hospital bed or at home. The non-intrusive device simply disappears into the object in which it is integrated and a variety of applications not only in healthcare is possible: e.g., when used in a car seat, the mat can monitor posture and driver alertness.
The size of the mat is limited only by the maximum size that can be handled by the printing equipment. We used screen printing to demonstrate this concept – there are screen printers that can print on substrates as large as 200 cm x 100 cm. For the purpose of demonstration, our mat is 90 cm x 60 cm in size.
- Healthcare: vital signs and posture monitoring at hospitals as well as home (remote patient monitoring)
- Automotive: driver monitoring
- Wellness: monitoring the posture and wellness of e.g., office workers
