High Stability of Diketopyrrolopyrrole Polymer Transistors Under Aqueous Condition Toward Biosensing Platform

open access: yesAdvanced Materials Technologies, EarlyView.
We are reporting the first‐time investigation of DPP‐based Organic Field‐Effect Transistor (OFET) devices with high‐stability of signal response in both of ambient and aqueous conditions with PBS solution. ABSTRACT Diketopyrrolopyrrole (DPP)–based conjugated polymers show strong promise for electronic applications, including bioelectronic gas sensors ...

Equivariant filtering framework for inertial-integrated navigation

open access: yesSatellite Navigation, 2021
This paper proposes an Equivariant Filtering (EqF) framework for the inertial-integrated state estimation. As the kinematic system of the inertial-integrated navigation can be naturally modeled on the matrix Lie group SE 2(3), the symmetry of the Lie ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
