Comparison of the current study to similar reported studies of on the usage of the dry electrodes when integrated with the IoT system.

Application	Materials	Method of Application and Limitation	Method of Evaluation	Reference
Smart textile for measuring trunk orientation	Embroidered-based conductive threads, HC-40 and C-70	Development and integration of sensor materials into textile garment, when full integration of IoT was not implemented	Electrode comparison	[33]
Electromyography (sEMG) recording	Graphene based textile electrode	Ozturk et al. utilized dip coating and sewing techniques to integrate electrodes into the bandage sleeve during the development of a sEMG device. However, when dip coating and sewing methods are compared to embroidery electrodes, the latter are often preferred for their comfort, durability, flexibility, customization options, and potential for better signal quality, especially when integrated into the IoT system	Performance evaluation	[34]
Electrocardiography (ECG)	Conductive fabric-based wearable device integrated with the IoT,	Sewn electrodes may be prone to loose contact with the skin during movement, leading to signal quality issues. In contrast, embroidered electrodes are seamlessly integrated into the fabric, reducing the risk of contact loss and improving signal quality, especially when used in IoT applications for continuous monitoring. The flexibility and customization options of embroidery also make it a preferred choice for wearable technology that requires reliable and high-quality sensor data.	Electrode comparison	[35]
