Objective:

To identify and prioritize the sensing material design characteristics that govern anticipated user acceptance of IMSU-enabled intimate physiological health monitoring devices and to determine the contribution of behavioral, hedonic, and identity-expressive acceptance pathways to overall adoption orientation.

Approach:

• Research Framework: The study integrates three theoretical frameworks: TAM for functional adoption mechanisms, UTAUT2 for hedonic motivation, and HDTB for user response dimensions.
• Methodology: A sequential FA–ANP mixed-methods design is employed to evaluate user acceptance.

Key Findings:

• User acceptability is a critical driver of wearable health technology adoption.
• Hedonic motivation is particularly relevant for intimate health monitoring devices.
• Existing frameworks (TAM and UTAUT2) require domain-specific extensions for intimate health contexts to enhance their applicability.

Interpretation:

The study highlights the need for user-centered design evidence and regulatory benchmarks in the development of intimate health monitoring devices.

Limitations:

• The existing literature lacks empirical accounts of how specific design characteristics shape acceptance outcomes.
• There is a tripartite deficit affecting patients, clinicians, and policymakers due to insufficient user-centered design evidence.

Conclusion:

The research aims to fill the knowledge gap regarding user acceptance of wearable health technologies, particularly in intimate health monitoring contexts.
