New publication: Unleashing the potential of industry viable roll-to-roll compatible technologies for perovskite solar cells: Challenges and prospects
In recent years, research on organic-inorganic hybrid halide perovskite solar cells (PSCs) has surged, achieving power conversion efficiencies exceeding 26%. Despite this progress, significant challenges hinder their commercial viability, including limited stability under typical environmental conditions and the lack of scalable manufacturing technology for perovskite film production. This review explores various deposition techniques used in…

New publication: Cyborg insect repeatable self-righting locomotion assistance using bio-inspired 3D printed artificial limb
A novel idea to assist in the cyborg insect locomotion. Using 3D printed parts inspired by the ladybug insect we can assist for the self-righting of the Madagascar cockroach. A combination of electronics and 3D printing with miniature actuators to work at low voltage will allow to repeat the motion multiple times. The insect can…

Multi-material 3D printing technology: integrated preparation of polymers and metals
Existing three-dimensional (3D) printing technologies, both polymer-based and metal-based, can only fabricate (only) plastic structures or (only) metal structures, which severely limits the application of additive manufacturing technologies in electronics such as IOT, ICT and robotics. Electronic devices are usually composed of both functional plastics and metals, including sensors and micro-actuators. They are connected together…

Reconstructed Attractor for Life State Detection
This study evaluates physiological states of organisms from a nonlinear system perspective. Taking the human body as an example, the running states of heart and blood vessels are obtained by collecting ECG and PPG signals, and the feature extraction of complex physiological signals is applied by chaotic attractor reconstructions. Digital life state monitoring will provide…

Mental Stress Assessment in Daily Life Using Electrocardiogram and Pulse Wave
It is believed that quantification and monitoring of daily stress can lead to prevention of various stress-related diseases. In this study, we integrated simultaneously measured electrocardiograms and pulse waves to calculate highly accurate stress values that are not easily affected by noise, and calculated the reliability of each biological signal in a defined analysis interval…

Simultaneous measurement of contractile force and field potential of dynamically beating human iPS cell-derived cardiac cell sheet-tissue with flexible electronics
Human-induced pluripotent stem (iPS) cell-derived cardiomyocytes are widely employed in global in vitro studies for both pharmacological and pathological research. Specifically, evaluating the functionality of heart tissues generated from these iPS cell-derived cardiomyocytes holds the promise of accurately predicting the effects of drugs, thereby streamlining the drug development process. Nevertheless, the existing method of assessing…

Wearable Electronics: Smart Face Mask Based on an Ultrathin Pressure Sensor for Wireless Monitoring of Breath Conditions
Deaths from sudden cardiac disease have been at a high level among causes of mortality during the past ten years, according to WHO statistics. Long-term ECG monitoring of the human body is frequently necessary for the approach of preventing and treating sudden cardiac illness. Many diseases, including sudden cardiac disease, will lead to minor alterations…
