Figure 4: The SGOTFT in acoustic wave detection.
From: Flexible suspended gate organic thin-film transistors for ultra-sensitive pressure detection
(a) Schematic illustration of device geometry for ultra-sensitive detection of acoustic wave. (b) Response of a sensor, integrated with 4 μm photoresist and 10 μm Al foil suspended gate, to the acoustic wave with a fixed frequency of 5 kHz. (c) Sound pressure sensitivity of SGOTFT. The error bars represent 1 s.d. (d) Electric signal response of a sensor to the same music for two times.
