Ultra-sensitive pseudocapacitive iontronic pressure sensor for wearable snoring and apnea detection

Year: 2024

Type: conference-paper

Abstract: Snoring is a common phenomenon, but its potential implications have been severely underestimated. In this study, we introduce a flexible pseudocapacitive iontronic pressure sensor with ultra-high sensitivity, achieved by combining MXene electrodes with ionic film. This pressure sensor demonstrates remarkable capabilities, including an ultra-high sensitivity of 3084.4 kPa−1, a comprehensive pressure range up to 300 kPa, an extremely low detection limit of 1 Pa, and superior stability. Utilizing its exceptional performance, the sensor has been effectively applied in respiratory monitoring, where it can precisely detect critical conditions such as snoring and apnea. This work has demonstrated its potential application prospects in medical monitoring.
