The examination of palmar grasp reflex is frequent in neonatal intensive care unit (NICU) to evaluate the neuro-sensorimotor developmental disorders and pathological abnormalities during the infancy period of clinically complicated neonates. In this study, we develop a wearable pressure sensing device to quantitatively measure the elicited palmar grasp strength of clinically complicated neonates aged 0–2 months. A capacitive pressure sensing device was fabricated using Ecoflex which acted as a dielectric material sandwiched between two copper electrodes, and further assembled with the coupling parts to provide comfort to neonates. The characterization of the fabricated device showed a linear sensitivity (0.13 kPa⁻¹), a high pressure range up to 530 kPa, and excellent working stability. Clinical experiments were performed on 33 newborns by investigating the laterality and hand preferences in male and female neonates, the development of palmar grasp behavior in the first three days of life, the influence of weight loss on palmar grasp reflex, and difference in palmar grasp strength of term and preterm neonates. The developed device was capable of measuring the elicited grasping reflex of neonates reliably, mimicking the conventionally used diagnostic method in NICU.

新生儿重症监护病房（NICU）经常进行手掌抓握反射检查，以评估临床复杂新生儿期婴儿期的神经感觉运动发育障碍和病理异常。在这项研究中，我们开发了一种可穿戴的压力传感设备，以定量测量0至2个月大的临床复杂新生儿的手掌抓握强度。电容式压力传感设备使用Ecoflex制成，它充当夹在两个铜电极之间的介电材料，并进一步与耦合部件组装在一起，为新生儿提供了舒适感。所制造器件的表征显示出线性灵敏度（0.13 kPa ^-1），高达530 kPa的高压范围以及出色的工作稳定性。通过调查男女新生儿的偏侧性和手部偏爱，出生前三天的手掌抓握行为的发展，体重减轻对手掌抓握反射的影响以及手掌抓握强度的差异，对33名新生儿进行了临床实验足月和早产儿。所开发的装置能够可靠地测量新生儿引起的抓握反射，从而模仿了NICU中常规使用的诊断方法。
