3、5/03/03IntroductionThis document is to let customer understand Mechanical Design for Consumer Products, such as Wearable Device.Basic Requirement: Using Surface Cover with Double InjectionAlso, PXI strongly suggests customer should use “step design” in order to improve contact between skin and senso

4、r. PXI suggests that the protrusion part should be 0.5mm (or higher).Based on the study, average SNR for step design is far better than flat design.Step Design ConceptProtrusion from Surface (0.5mm or Higher)Note: tolerance +/-0.1mmA. Protrusion thickness Min: 0.5mm Max: 2.5mmB. Protrusion Area Min:
