A review paper by scientists at Institute of Chemistry, Chinese Academy of Sciences summarized the progress of biointegrated flexible and stretchable optoelectronics for wearable and implantable cardiac healthcare.
The new review paper, published on Oct. 18 in the journal Cyborg and Bionic Systems, focuses on the advances in biointegrated flexible and stretchable optoelectronics for wearable and implantable cardiac healthcare systems.
With the prevalence of cardiovascular disease, it is imperative that medical monitoring and treatment become more instantaneous and comfortable for patients. Recently, wearable and implantable optoelectronic devices can be seamlessly integrated into the human body to enable physiological monitoring and treatment in an imperceptible and spatiotemporally unconstrained manner, opening countless possibilities for the intelligent healthcare paradigm. “To achieve biointegrated cardiac healthcare, researchers have focused on novel strategies for the construction of flexible/stretchable optoelectronic devices and systems.” explained study author Yunlong Guo, a professor at Institute of Chemistry, Chinese Academy of Sciences. Thus, they summarized the advances in wearable and implantable optoelectronic devices for cardiac healthcare. They focused on the stretchable design, device-biological tissue interface design and encapsulation design of biointegrated optoelectronic devices. Then, the authors moved on to the examples of cardiac physiological monitoring, optogenetic and non-genetic stimulation by biointegrated optoelectronic systems.
Looking forward, the development of high-performance intrinsically stretchable optoelectronic materials is of primary importance in the future. Meanwhile, further research on the processing of intrinsically stretchable optoelectronic arrays with high device densities is also an important direction in the future. The key to realizing intrinsically stretchable optoelectronic arrays with high device density is the construction of high-density electrode arrays. This is expected to be achieved by combining photolithography processes or high-resolution printing techniques such as electrohydrodynamic printing. And it is also possible to introduce dynamic self-healing units to repair the charge transport pathways after undergoing repeated strains.
“The improvement of materials science, fabrication processes and integration technologies will address the current challenges and further promote the clinical translation of bio-integrated optoelectronic platforms towards the next-generation smart healthcare terminals,” said Li.
Authors of the paper include Cheng Li, Yangshuang Bian, Zhiyuan Zhao, Yunqi Liu and Yunlong Guo.

It takes a lot to succeed with ambitious goals. Among other things, we need passion and belief that we will succeed, and we usually need support from others.
However, we also need to have the right attitude – the right mindset, one that makes us willing to do what it takes to change and improve. Experts refer to it as a growth mindset.
So, how do we know if we actually have the right mindset? How can a coach know if a talented athlete has the mindset needed to become one of the best? An individual’s mindset is influenced by external factors that can change, and it may also vary from day to ...

WASHINGTON—A vigorous workout does more to suppress hunger levels in healthy adults than does moderate exercise, and females may be especially susceptible to this response, according to a small study published in the Journal of the Endocrine Society.
The study examines the effects of exercise intensity on ghrelin levels and appetite between men and women. Ghrelin is known as the “hunger hormone” and is associated with perceptions of hunger.
“We found that high intensity exercise suppressed ghrelin levels more than moderate intensity exercise,” said lead author Kara Anderson, Ph.D., of the University ...

Decades after it was first found in Japan, a species of crustacean with unique black-and-white coloring that resembles a panda has been confirmed to be new to science. Melitid amphipods are shrimp-like crustaceans found worldwide. The newly classified Melita panda — named after the charismatic mammal — was first found in the 1990s. Details of the discovery and morphological analysis were published in a ZooKeys article on 21 September.
The discovery of the Melita panda highlights the importance of studying species taxonomy, which is the naming and classification of organisms, for conservation efforts. It is impossible to know if a species is in ...

BOSTON (Oct. 24, 2024) – With the rise in incidence of food allergies in children in the past decade, there has been a corresponding increase in the need for professional psychology services due to increased anxiety. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed a more than 50% increase in psychology referrals at one center in 2023 compared to yearly referrals from 2018-2022.
“Our center has devoted significant resources to address the psychosocial support needed by many families who have children with food allergies,” ...

BOSTON (Oct. 24, 2024) – Anaphylaxis can come on suddenly and without warning, and because its symptoms can be fatal, it is scary for those who encounter it. Two new studies being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston show it is not only patients and caregivers who misunderstand how best to treat anaphylaxis: emergency medical professionals often follow incorrect protocols for treating severe allergic reactions.
“We know early recognition of anaphylaxis and treatment with epinephrine improves outcomes,” says Sasha Alvarado, DO, Co-Director of Quality ...

BOSTON (Oct. 24, 2024) – About 10% of Americans believe they are allergic to penicillin, and approximately 90% of those patients are not actually allergic. As a result, those with the penicillin allergy label are often prescribed more toxic, dangerous and expensive antibiotics that might not be necessary or effective. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that syphilis patients labeled as penicillin allergic who are low risk should be delabeled to avoid treatment failure and other negative ...

BOSTON (Oct. 24, 2024) – Parents of children with atopic dermatitis (AD, also called eczema) know that the allergic condition can mean a heightened risk of developing food allergies. The desire to prevent food allergies causes some parents to consider elimination diets, cutting out certain foods from their child’s diet. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that elimination diets in the case ...
