Advanced Science, EarlyView.A transfer‐free fabrication method enables multilayer graphene microelectrodes as small as 10 µm, eliminating reliability issues of manual graphene transfer. These electrodes record neural activity in brain slices with exceptional signal‐to‐noise ratios (up to 25–40 dB) while maintaining optical transparency for multimodal applications.

New Current-Mode Bandpass Filters Using Three Single-Output ICCIIs
Active and Passive Electronic Components, 2007 New current-mode bandpass filters using three single outputs inverting second generation current conveyors (ICCII) are introduced. The first circuit uses two ICCII+ and one ICCII−, and realizes an inverting bandpass response.

Advanced Science, EarlyView.A brain‐adhesive sensor (B‐Sensor) was developed by integrating a self‐healing biodegradable elastomer, a tissue‐adhesive hydrogel, and molybdenum electrodes. The B‐Sensor adheres to brain tissue, conforms to cortical curvatures, and maintains stable electrical performance over the intended period for reliable recording of spatiotemporal brain activity

DIRECT SYNTHESIS OF LADDER WAVE DIGITAL FILTERS WITH TUNABLE PARAMETERS
ASEAN Journal on Science and Technology for Development, 2017 This paper proposes a method for the synthesis of ladder wave digital filters (WDFs) directly from the digital domain. This method avoids the need for the synthesis of analog reference filters conventionally required in WDF design.

IEICE Electronics Express, 2007 In this paper, a super ultra-wideband (UWB) bandpass filter (BPF) with frequency bandwidth from 3.0GHz to 22.5GHz (-10dB-return loss bandwidth), which is much wider than that of the conventional UWB BPF, was proposed and demonstrated. The filter employed a simple and compact broadside-coupling structure.
