Multisensory modelling of wetness perception during baby hygiene absorbent products interactions

该项目将基于Davide Filingeri博士的S博士最近发现的人类皮肤湿感的神经机制，使用一种新的多感官神经科学方法，对婴儿卫生保湿产品相互作用过程中的湿感进行调查和建模。婴儿的湿感是影响卫生吸湿性产品舒适性和可接受性的最关键因素，其中婴儿尿布就是其中之一；然而，在婴儿吸湿性产品的相互作用过程中，我们对什么感官提示(即视觉、温度、触觉、气味、声音)对湿感的影响知之甚少。婴儿尿布是独特的吸湿性产品，因为它们的舒适性和可接受性主要由婴儿的照顾者而不是佩戴者(即婴儿)来评估。这对理解产品的哪些方面以及护理者和婴儿之间的交互可以被改进提出了重大挑战，以减少湿润的感觉，并最大限度地提高护理者和佩戴者在更换尿布期间的舒适性。本研究将人类感官神经科学应用于产品工程，旨在：1.在标准化的护理者/婴儿更换尿布的场景中，量化不同感官提示(即视觉、温度、触觉、气味、声音)对湿润感知的个体和交互贡献；2.确定感觉提示之间的任何附加的、协同的或对抗的交互作用；3.开发首个在婴儿吸收产品相互作用过程中导致湿感的生物物理和感知因素的经验模型；产生的知识将为人类多感官整合的神经机制提供新的见解，并将支持以用户为中心的创新-为婴儿和成人设计和设计更舒适和有效的卫生吸收产品。

This project will investigate and model wetness perception during baby hygiene absorbent products interactions, using a novel multisensory neuroscience approach that is based on Dr Davide Filingeri' s recent discovery of the neural mechanisms underlying human skin wetness perception. The perception of wetness is the most critical determinant of comfort and acceptability of hygiene absorbent products, amongst which baby nappies; yet we know very little on what sensory cues (i.e. visual, thermal, tactile, smell, sound) contribute to wetness perception during baby absorbent products interactions.Baby nappies are unique absorbent products, as their comfort and acceptability is primarily assessed by the baby's caregiver rather than by the wearer (i.e. the baby). This poses a major challenge to understanding what aspects of the product and of the interaction between carer and baby can be improved, to reduce wetness perceptions and maximize carer and wearer's comfort during nappy changes.Using a unique mix of human sensory neuroscience applied to product engineering, the proposed research aims to:1. Quantify the individual and interactive contribution of different sensory cues (i.e. visual, thermal, tactile, smell, sound) to the perception of wetness during a standardised caregiver/baby nappy-changing scenario;2. Identify any additive, synergistic or antagonistic interaction between sensory cues;3. Develop the first empirical model of the biophysical and perceptual factors contributing to wetness perception during baby absorbent products interactions;The knowledge produced will provide novel insights on the neural mechanisms of multisensory integration in humans and will support innovation in user-centered-design and engineering of more comfortable and effective hygiene absorbent products for both babies and adults.
