Mobile invivo microrobot for measuring intercranial pressure

Versatile disposable sensor
This disposable absolute pressure sensor, as installed in the microrobot, provides accurate and stable values in the range of -300 mmHg to +500 mmHg, which is of interest for clinical use, and can remain in the body for several days. The sensor is intended for applications in air and saline liquids such as blood, cerebrospinal fluid or urine. This makes it suitable not only for monitoring invivo brain and eye intervention, but also for the use in arteriosclerosis and in urology.
Also suitable for catheters with only 1 French diameter, Amsys GmbH & Co. KG is presenting the smallest absolute pressure sensor for invivo pressure measurements at Compamed in Düsseldorf this year. The sensor, measuring just 750 × 220 × 75 µm, is already connected to a highly flexible, fully protected cable for easy use.

Evaluation kit with calibrated sensors
For an easy start with the IntraSense, an evaluation kit with several already calibrated sensors is available. After connecting the evaluation board to a USB interface, the pressure and temperature signals from the sensor can easily be read out using the free open-source Arduino software. The sensors are available from Amsys either as uncalibrated or calibrated standard version, with two standard cable lengths (60 cm or 180 cm) or as a extra light-protected version.

The innovation
The french company Robeauté is pushing boundaries with a tremendously powerful active device concept, at the opposite end of the passive microrobotic consensus: a fully equipped microrobot, developed for in vivo intracerebral 3D navigation. This microrobot concept consists of two parts: (1) the standard part composed of a micropropulsor, a microengine, a microelectronics and micro-wires for power and communication, and (2) the additional ICP micro-sensor a plug-in-extension, which can be adapted to different surgical interventions (microsensors, microelectrodes, micro-cameras, etc.).
