eAir (sensors for robotic surgeons)

2023: Product Announcement

On August 18, 2023, researchers from the National University of Singapore reported on the development of an aeroelastic eAir pressure sensor for robotic surgery systems. The product provides tactile feedback, which allows doctors to more accurately manipulate the patient's tissues.

Scientists say that conventional pressure sensors are often unable to provide sufficient accuracy. Such articles may give inconsistent readings, show different results when measuring the same pressure again, and miss minor pressure fluctuations. All this leads to significant errors, which can result in a deterioration in the quality of the medical care provided. In addition, standard sensors are usually made of rigid materials that are not able to bend. The new solution of Singaporean specialists allows you to bypass the existing restrictions.

The development uses the so-called lotus leaf effect. Its essence lies in the fact that water falling on the leaves coils into ball-shaped drops, which easily roll off the surface. The effect is due to the peculiarities of the microbuilding of the plant, as well as the high hydrophobicity of the leaves. Simulating a natural phenomenon, the project participants developed a sensor capable of recording even the most minor pressure changes.

The eAir sensor contains an air membrane that takes indicators from the border between air and liquid. As the external pressure increases, the air layer contracts, causing electrical signals to change. This reflects the pressure exerted with high accuracy. The sensor can be used in laparoscopic operations where highly effective tactile feedback is required. In addition, the product offers less invasive means of monitoring intracranial pressure - the main indicator of the health of people with neurological diseases.^[1]
