Abstract: Wearable electronics are increasingly integrated into healthcare, sports, and personal devices, requiring circuits that are compact, low-power, flexible, and
robust. Circuit design for wearables presents unique challenges, including power constraints, form factor limitations, mechanical stress, and environmental variability. This paper reviews critical aspects of wearable
electronics circuit design, including low-power analog and digital design, sensor interface techniques, energy harvesting integration, and flexible substrate implementation. Practical design strategies are analyzed, and comparative tables illustrate trade-offs in size, power, and performance. Future trends in wearable circuit design, including flexible electronics and ultra-low-power processing, are discussed.
