PDMS-Based Capacitive Pressure Sensor for Flexible Transparent Electronics

الملخص EN

We propose a flexible pressure sensor based on polydimethylsiloxane (PDMS) and transparent electrodes.

The transmittance of the total device is 82% and the minimum bending radius is 18 mm.

Besides, the effect of annealing temperature on the mechanical properties of PDMS is reported here.

The results show that the PDMS film under lower annealing temperature of 80°C has good compression property but poor dynamic response.

While for higher temperatures, the compression property of PDMS films significantly reduced.

The best compromise of annealing temperature between compression property and dynamic response is found for PDMS film of about 110°C.

The pressure sensor under 110°C curing temperature shows a good sensitivity of 0.025 kPa−1 and robust response property.

The device shows a promising route for future intelligent transparent sensing applications.
