**A materials scientist combines two polymers to enhance sensor flexibility. Polymer A makes up 60% of the composite and stretches 15%, while Polymer B stretches 25%. What percentage of the composite is Polymer B, and what is the overall stretch?** In an era driven by smarter, more responsive sensor technologies, a key breakthrough lies in how modern materials scientists blend polymers to achieve unprecedented flexibility. This innovation is gaining attention as industries seek lightweight, durable components for wearable tech, flexible displays, and advanced industrial sensors. **Why A materials scientist combines two polymers to enhance sensor flexibility.** Polymer A makes up 60% of the composite and stretches 15%, while Polymer B contributes 25% of the formulation and stretches 25%. This strategic mix balances performance and resilience—exactly what engineers demand when designing next-generation flexible electronics. To understand the composite’s ability to stretch, we calculate the weighted average stretch. Polymer A accounts for 60% and stretches 15%, contributing 9% to the total stretch proportionally. Polymer B, making up 25% of the blend, stretches 25%, adding 6.25% to the effective stretch. Combined, these translate to a total stretch of 15.25%. Since Polymer B comprises 25% of the composite, the percentage of Polymer B remains clearly defined at 25%. The overall stretch—accounting for material proportions—is 15.25%, a figure that demonstrates how precise polymer blending enables predictable, high-performance flexibility.
