description | As healthcare systems worldwide face resource limitations, governments and research
institutes are investing more into preventative healthcare initiatives. In this regard,
conformal bioelectronics hold a significant advantage over conventional bulky and
rigid equipment in terms of portability and user experience. However, the lack of
mature flexible electronics ecosystem is a limiting factor for their development. To
address the mechanical property mismatch between rigid microelectronic components,
flexible substrates, and human tissue, a technique to unify these materials cohesively
is urgently required to provide a reliable platform for future innovation. In contrast to
various proposed methodologies, this project presents screen-printing of electronic
circuits using silver electronic paste for fabricating conformal wearable devices. This
study demonstrated the feasibility and benefits (simplicity, versatility and scalability)
of this approach by fabricating a 3-lead ECG bilayer circuit on a PDMS substrate. The
resulting product was thin, comfortable, and imperceptibly transparent whilst
conforming tightly to the epidermis. Preliminary characterization presented high
resolution patterns with low contact resistance at ±2Ω and negligible variance in width
modulation for fine prints at sub-millimetre scale. By incorporating viaholes in the
circuit design, multilayer circuits can be fabricated to fit multiple functions in a small
area. In summary, this research serves as a feasibility study for initiating the
development of novel flexible bioelectronics with broad applications, particularly for
monitoring biophysiological signals. |
