Unless it is lying directly in the hospital bed, the medical institution has the opportunity to put an instrument next to the patient to measure physiological data such as heart rate, blood pressure, blood oxygen concentration and other long-term; ordinary people are unlikely to live in life unless they buy wearable equipment. It is useful to monitor the body for a long time, and they are all sticky or close to the skin. What if it is directly attached to your internal organs? Is it convenient and more "close to the truth"?
A study published in the journal Nature Communications, which combines two technology products, opens up a new way to attach micro-detectors to the surface of living organisms as a long-term monitoring of physiological data. It works by attaching a sticky gel to a "circuit board" that is thinner than cling film and attaching it to the heart of a living mouse. The above picture is an example of the use of this gel. It consists of polyrotaxane, polyvinyl alcohol and a photoinitiator, which can be used to bond a Japanese hundred dollar coin.
Using this technique, the research team can detect the beating of the heart of the mouse and the stimulation of the myocardial cell discharge. In the experiment, the gel effectively maintained a good condition for three hours.
In addition to the role of the gel, another highlight of the study is the ultra-thin and bendable "circuit board." It was published in 2013 by Professor Denya Takashi of the University of Tokyo's electrical engineering. In this paper, they also took the opportunity to demonstrate its use: stick it on the finger joints, and when the joints are stretched, they are not only functional. Influence, but also detect motion.

This circuit has only one-fifth of the cling film and one-thirtieth of the thickness of the A4 paper. The dyed valley describes it as "the thin piece of the sanitary napkin advertisement, which makes me almost forget its existence." This one-micron-thick sheet technology comes from Polyethylene Naphthalate (PEN), which can be made to 10 cm thick or 10 km long, and can be used as a capacitor by electronics manufacturers. use. In the field of medicine or health care, it has become a new interface for wearable devices to detect human physiological conditions, and can also be applied to implantable devices in the human body. However, the research team said that the potential of this technology is endless, and many applications will emerge one by one.
