Developing a elastomeric wearable sensor with good conformity and proper contact to skin,
coupled with the capability of monitoring various physiological parameters, is very crucial for
the development of point-of-care sensing devices with high precision and sensitivity. While
there have been previous reports on the fabrication of elastomeric multifunctional sensors,
research on the printable elastomeric multifunctional sensor is not very well explored. Herein,
we will discuss about the development of a stencil printable multifunctional elastomeric
sensors. The sensors demonstrated the capability of having good contact with skin and its ability
to function as a temperature and strain sensor. Different elastomers were selected as the matrix
while carbon nanomaterials were used as the nanofiller. The selection of the above model
compounds facilitated the printability and also helped the same composition to demonstrate
stretchability. In addition to the printable elastomeric sensors, discussion will be also made on
the recent efforts on the development of recyclable sensors made out of thermoplastic
polyurethanes. In both the classes of sensors, various physiological parameters like motion
sensing, pulse, respiratory rate, and phonetics detection were detected by leveraging the
electrically resistive nature of the sensor. This development route can be extended toward
developing different innovative compositions for point-of-care sensing applications. |
