Co‐Design Insights for Mechanically Active Flexible Printed Circuit Boards Through the CurveQuad Origami Robot

Advanced Science, EarlyView.
This paper presents the process of integrating electronics directly into the body sheet of CurveQuad, a small origami robot that can self‐fold, crawl, and steer with a single actuator. The authors design a flexible printed circuit board for the body sheet: the key challenge is to navigate how embedding electronics affects the mechanical properties and ...

Contact‐Free Human‐Machine Interfaces via Printed Thermopile Infrared Arrays

Advanced Science, EarlyView.
Can a printed sheet locate and sense a fingertip without being touched? Fully printed, flexible thermoelectric arrays convert the infrared from a hovering finger directly into voltage, with no external power. Aerosol‐jet‐printed silver mirrors partially shield each pixel, creating a local temperature gradient.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Reference Electrode‐Free Nitrate Sensing via Differential Temperature‐Modulated Potentiometry in Printed Symmetric SC‐ISEs

Advanced Electronic Materials, EarlyView.
This work proposes and validates a method for measuring nitrate concentration with printed, solid‐state ion‐selective electrodes that does not require a stable reference electrode. The approach uses brief, localized heating pulses to generate a concentration‐dependent voltage response that is drift‐resilient and log‐linear from 0.1 to 100 mm, while ...
