Engineers from Columbia University in the United States have created the world’s smallest single-slide system that can be implanted with a needle under the skin to measure internal body temperature and for other purposes.
The continuous miniaturization of electronics provides exciting opportunities for anyone to place in the body to control and improve their health. It is interesting that scientists have succeeded in developing a fully functional electronic circuit, which is characterized by its small size and seen in the image on the tip of a needle.
The innovative single-chip system, much smaller than the world’s smallest computer, is a cube-shaped device that measures 0.3 mm on each side.
The scientists use a piezoelectric transducer to wirelessly operate the tiny chip and communicate with it via ultrasound. Along with the built-in sensors, this micro-device transforms an electronic implant into a system for measuring various health indicators.
And now there is talk about measuring body temperature, but among other possibilities that may appear, scientists add measuring blood pressure and glucose levels, as well as analyzing the state of the respiratory system.
In practice, the single-slide system was tested on live mice, and the device was implanted in several rodents by intramuscular injection. Scientists also discovered that they had succeeded in using tiny implants to stimulate nerves by ultrasound.
