The project involved more than just fabricating a sensor and attaching it to a subjectвЂ™s chest area.

To test the patch itself and establish baseline specifications for applied stress versus resultant strain output, they used a tensile-testing load frame and instrumentation (Figs. This piezoelectric polymer was patterned into a serpentine mesh by a mechanical cutter plotter for a final mesh size of 38.1 mm Г— 18.1 mm (Fig. The sensing patch consists of a 28-Ојm-thick polyvinylidene fluoride (PVDF) film with 80-nm thick Cu-Ni electrodes on the top and bottom surfaces.

This sensor can be worn for several days while providing constant heart monitoring, a major advantage over brief, вЂњat the doctorвЂќ hookups and readings. Furthermore, although itвЂ™s not the first ECG-sensing tattoo, the others are fabricated from non-stretchable materials, making them bulky and uncomfortable for wear beyond short periods. The UT team claims itвЂ™s the first ultra-thin and stretchable technology to measure both ECG and SCG. The e-tattoo made of polyvinylidene fluoride, a piezoelectric polymer, is remotely powered by a smartphone. вЂњWe can get much greater insight into heart health by the synchronous collection of data from both sources,вЂќ noted project leader Nanshu Lu, an associate professor in the departments of Aerospace Engineering and Engineering Mechanics and Biomedical Engineering. When combined with ECG data, it helps assess the accuracy of the ECG readings. SCG is a measure of chest vibrations associated with heartbeats and provides additional information. Simultaneously and time-correlated, it also provides less-known seismocardiograph (SCG) readings. A multidisciplinary team based at the University of Texas (Austin) Cockrell School of Engineering has developed and tested a flexible, comfortable, long-lasting, piezo-driven wearable electronics tattoo (e-tattoo) that can be placed on the skin, and it captures cardiac health-related data in two ways.ДЇirst, it captures the well-known electrocardiograph readings (ECG or EKG). Modern materials science and fabrication techniques are enabling diverse avenues for innovation in the area of medical sensors that go beyond established basics.
