Flexible Sensor Gains Sensitivity Under Pressure

Flexible Sensor Gains Sensitivity Under Pressure

Pressure sensors are expected to stay accurate across everything from gentle touch to strong, shifting loads. Yet many flexible designs are most sensitive only at low pressure, losing resolution as the force rises. Now, researchers have developed a tunable flexible capacitive pressure sensor that does the opposite: it becomes more sensitive as pressure increases. Built from a flat precursor that transforms into a three-dimensional cage-like stru…
