2022年10月17日 · In this review, advances in OECT-based sensing systems are systematically summarized, with a focus on the OECT-based sensing array. Furthermore, perspectives, concerning stability, cut-off frequency, integrating density, and power dissipation, are discussed based on recent studies on OECTs and their relevant sensor arrays.

2025年1月7日 · Here, we present an AI-assisted sweat-sensing device using an inkjet-printed ion dynamics-differentiated OECT array (Figures 1 A and 1B). The device utilized the ion-electron coupling dynamics of OECTs to detect ions in sweat and map the dynamic response curve into multivariate sweat fingerprints to be classified using AI.

2024年10月2日 · In this Article, we report the scalable fabrication of micro-ISOECT arrays and their integration into a wearable integrated and soft electronic (WISE) platform (Fig. 1). The WISE platform is...

2025年1月1日 · In recent years, organic electrochemical transistors (OECTs) have emerged as a promising tool to add to current analytical methods due to their high-amplification capacities, robust analytical performance, and versatility. The present work proposes a compact multi-analyte transistor array with outstanding analytical performance.

2023年4月27日 · Here we report an organic electrochemical transistor capable of sensing, memory and processing. The device has a vertical traverse architecture and a crystalline–amorphous channel that can be...

2023年3月25日 · We demonstrate that organic electrochemical transistors (electrolyte gated transistors with volumetric gating) can serve as on-site amplifiers to improve the sensitivity of electrochemical...

2023年11月15日 · These OECT arrays were subsequently implanted on the somatosensory cortex of rats to record ECoG signals (Figure 6 E). Accurate identification of the regions of the brain that generate high-frequency oscillations or microseizures was successfully achieved.

An OECT array was then implanted into the ventral tegmental area, a key region involved in dopaminergic signaling, enabling mapping of evoked dopamine release in multiple striatal brain regions under different physiological conditions.

2023年2月2日 · Herein, ultra-flexible organic electrochemical transistor (OECT) arrays used for wearable ECG mapping on the skin surface above a human heart are presented. QRS complexes of ECG signals at different recording distances and directions relative to the heart are obtained.

4 天之前 · As shown in Fig. 5, the channel resistance of the OECT increases until it reaches equilibrium, after which the response stabilizes. By applying a gate voltage modulation between 0 and 0.6 V, or between −0.6 and 0.6 V, the sensor tends to return to its initial values, indicating its potential as a non-disposable sensor.
