The effect of our pressure sensor is S = (ΔI / Ioff) / ΔP, where ΔI is the change in current, Ioff is the effect of no-load current and ΔP is the change in applied pressure. The approximate relationship between ΔI/Ioff and applied pressure P in the range 0–5 kPa leads to a theoretical value of S=1.14 kPa−1. This value is only near the record for an organic transistor pressure sensor3 and is higher than the sensitivity of 5 ×
10-3-0.55 kPa-1 for other pressure sensors with a sensing area of ​​0.6 × 0.6 mm2. -8 × 8 mm (refs. 22, 34, 35, 36, 37). In addition, higher sensitivity can be achieved by increasing the coverage area of ​​AuNWs (Supplementary Fig. 7) and reducing the thickness of PDMS (Supplementary Fig. 8).

Little deformation was observed at a pressure of 600 Pa at 1 Hz (Supplementary Fig. 1). The length and shape of the line remained constant with the increase of the force at 0 Pa (Supplementary Fig. 10c), resulting in a response time of 17 ms. , A piezoelectric stepper with a minimum displacement of only 1 μm was used to measure dynamic deformation in an AuNW-based sensor. No. 4a. as shown in the figure, a pressure of 13 Pa can be found, which corresponds to the weight of a drop of water at a height of 10 mm2 (~13 μl). For larger pressure changes, a noise-free response and a continuous stable response can be observed up to a pressure of 2600 Pa (Figure 4b).

(b) Plotting the response of the current sensor as a function of time (pressure frequency: 1 Hz) for applied pressure in the range of 75–2600 Pa. used to determine bending and bending strength. Interestingly, the response curves were common for all active power types in the same device (Figure 5 and Supplementary Movie 1). A high signal-to-noise ratio was observed for all three power measurement models, which further demonstrates the high sensitivity of the AuNW pressure sensor. The device also showed a stable response in the power range of
(Fig. 11 and supplementary table 1).
Since everyone who drives change expects the desired effect to happen, performance testing is critical to customer satisfaction. Only careful inspection by the manufacturer of any replacement can ensure that defective or defective parts are rejected at an early stage. In such a test, a sensor is used to measure the effort required to activate the switch. A “good” or “bad” quality depends on the power and distance strategy.
