Examining stress-avoiding techniques to reduce elastic mechanical energies.
Investigating strain-compliance, strain-resistance, and stress-damping approaches.

Main Results:

Hardware-based preprocessing offers an alternative to software-based methods for noise reduction.
Reducing mechanical stress on bioelectronics is key to preventing motion artifacts.
Various material and structural designs show promise in mitigating noise.

Conclusions:

Hardware-based noise reduction is crucial for reliable bioelectronic devices.
Further research should optimize materials, structures, and processing methods.
Advancements will lead to more effective bioelectronics for healthcare monitoring and diagnostics.
