Engineers have created an ultra-small electronic device that can measure the temperature inside a person
The engineers managed to design and create a fully working single-chip electronic circuit. Moreover, it is so small that it easily passes through a medical needle. The engineers managed to accommodate in such a small space a working system capable of measuring temperature and transmitting the collected data using a wireless transmission.
New development and its purpose
An engineering group at Columbia University managed to create such a small electronic device. So, in a volume of 0.1 cubic millimeter, scientists managed to arrange a fully working system for measuring temperature and wireless transmission of the received data.
This development turned out to be record low that it can be administered even with medical injections.
The device itself turned out to be so small that the antenna, which was located inside, turned out to be less than the length of the radio waves. Therefore, in order to communicate with the device, the engineers found the following way out.
To communicate with the device, it was decided to use ultrasound, which is recorded and transmitted using an internal piezoelectric element. In addition, a temperature sensor was placed in the body, the data from which is transmitted using ultrasound to external receiving devices.
It was decided to test the performance of the product on laboratory mice. So the investigated mice were introduced to seven of these "sensors", which successfully measured and transmitted the temperature of the animal.
In another series of experiments, the product was used to stimulate neurons in a targeted manner using an ultrasound signal.
Scientists shared the results of the experiments on the pages of the online journal Science Advances.
Engineers do not plan to stop at the achieved result and also plan to develop miniature devices for monitoring blood pressure, oxygen saturation and even glucose content.
Well, progress does not stand still, and perhaps in the near future we will see innovative devices that will allow us to determine as accurately as possible a dozen of extremely important parameters.
