Newly developed self-powered sensor can now offer hope for monitoring heart failure, reports a new study. The findings of the study are published in the journal Advanced Functional Materials.
Chinese scientists have designed an implant and self-powered sensor that can help monitor heart failure, a global public health problem in which the heart is incapable of pumping sufficient blood to meet the body's needs.
Congestive Heart Failure
Congestive heart failure (CHF) is a condition in which the heart fails to work adequately as a pump that can deliver oxygen rich blood to the body.

Based on the triboelectric nanogenerator that can convert bio-mechanical energy into electricity, scientists from the Beijing Institute of Nanoenergy and Nanosystems affiliated with the Chinese Academy of Sciences, to develop a miniaturized self-powered sensor that can enter the heart with minimally invasive surgery, Xinhua news agency reported.
The sensor is 1.5 cm long, 1 cm wide and 0.1 cm high. It has been experimented on pig models and integrated with a surgical catheter for minimally invasive implantation.

New study sheds light on how diabetes causes heart failure. Methylglyoxal (MG) is a glycolysis byproduct which is accelerated under diabetic conditions, modifies the cardiac myofilament more in diabetic heart failure patients.
It can conduct ultra-sensitive, real-time monitoring, and has mechanical stability. It can also detect ventricular fibrillation and ventricular premature contraction.
According to Liu Zhuo, one of the researchers, the study may help encourage the development of more miniature implantable medical sensors for monitoring and diagnosis of cardiovascular diseases.
"The sensor is promising for clinical application. This work also provides new ideas for the research of miniaturized implantable self-powered medical devices," Liu said.
The endocardial pressure is a key parameter for assessing cardiac function and has important clinical implications for patients with heart failure.
Endocardial pressure is commonly monitored by invasive and expensive cardiac catheterization, which is not feasible for long-term, continuous data collection.
There is an urgent need to develop a minimally invasive, high-sensitive and low-cost sensor to monitor endocardial pressure in real time, which would be of great significance for cardiovascular disease diagnosis and treatment, the researchers noted.
