Paragraph starter

The development of flexible pressure sensors often faces a trade-off between high sensitivity and a wide linear range. This research by Chen et al. (2023) presents an 'elegant strategy' utilizing nonlinear synergy between a pyramidal carbon foam array and an elastomer spacer. This combination achieved an unprecedented sensitivity of 24.6 kPa⁻¹ and an ultra-wide linear range of 1.4 MPa, attributed to the interplay of the sensing layer's nonlinear piezoresistivity and the regulator's nonlinear elasticity. This approach offers a valuable precedent for designing high-performance sensors in fields like soft robotics and wearable technology.
