Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Study on the Key Design Technology of the Laminar Plasma Torch:Double Arc Phenomenon

open access: yes工程科学与技术, 2017
:Segmented anode structure is always used to the structure design of the laminar plasma torch to avoid the large scale shunting,which would result in a pulsation of the laminar plasma jet.However,when the length of the inter-electrode is longer than its ...

Images of Arc-Heated Supersonic Argon Plasma Jet Impinging on a Flat Plate

open access: yes, 2011
Low-density flow fields are usually difficult to visualize using ordinary optical methods. However, plasma flows, having high temperature or excited species in them, may show up some features of the flow field in a simple photograph.

Modular Electronic Microrobots With Onboard Sensor‐Program‐Steered Locomotion

open access: yesAdvanced Intelligent Systems, EarlyView.
Modular electronic smartlet microrobots integrate ambient‐light energy harvesting, photodetection, programmable CMOS control, and bubble‐based actuation within a sub‐millimeter fold‐up architecture. A 58‐bit on‐board CMOS chiplet enables sensor–program steered switching between independently addressable actuators, achieving closed‐loop 2D navigation in
