Extended Data Fig. 7: Taxonomy of compliant, resistive sensing mechanisms.
From: Ultra-sensitive and resilient compliant strain gauges for soft machines
Red crosses in the strain response row indicate the point at which the sensor typically fails (the strain value at failure is indicated in blue text). The ultra-sensitivity determination is based on the linear gauge factor of the sensor (as opposed to the absolute gauge factor; see Extended Data Table 3). For each of the four categories at the bottom of the table, a green check indicates that ultra-sensitivity (linear gauge factors >1,000) has been demonstrated, off-axis deformation rejection has been shown, the ability to withstand cyclic loading >500 cycles has been demonstrated, and the conductors used have high resilience (as defined in Extended Data Fig. 5d), respectively. A red cross indicates where the above criteria have not been met. Data are from this work and refs. 9,11,18,21,22,25,26,29,43,44,45,46,47,48,49,52.
