New implant technology for measuring intracranial pressure

Wireless sensors implanted inside the human body can enable more efficient examination and treatment of illnesses in the future. TUT is at the leading edge of research in this field. One solution currently under development is a wireless system for long-term monitoring of intracranial pressure.
“The sensors carry a huge potential for commercialisation - after all, they can save human lives,” Mohammad Behfar believes.

Physiological parameters of the human body, such as intraocular or cardiovascular pressure, can be monitored more effectively than before with the help of passive, wireless sensor implants placed inside the body. The sensors can provide long-term data about the body without the need for an implanted battery. Indeed, wireless passive sensors are considered a promising alternative to the catheter-based solutions currently in use.

Tampere University of Technology (TUT) has a long history in researching wireless technologies, RF technologies, and sensors in research groups such as WISE (Wireless Identification and Sensing Systems Research Group) led by Professor Leena Ukkonen. WISE research concentrates especially on health technology applications. One of the group’s latest achievements is an implant technology solution for measuring intracranial pressure (ICP). 

From high-level international research to the biomedical market

Doctoral Student Mohammad Behfar has worked with the WISE research group in connection with his doctoral dissertation, and he has developed a sensor implant capable of measuring ICP in the long-term.

In Behfar’s proposed measurement system, a sensor implanted inside the patient’s skull communicates with an external reader device and a computer programme that allows for the ICP data to be measured and monitored in real-time.

The performance of the proposed prototype system developed at TUT was recently validated in vivo in close collaboration with the Biodesign Laboratory at University of California, San Francisco (UCSF). Behfar has worked in California for a total of seven months.

“Current research results are promising. This is an important step towards clinical trials. The solution we are developing will also be a cheap and effective way of measuring ICP,” says Behfar. 

The technology has every chance to enter the biomedical market.

“The sensors carry a huge potential for commercialisation ─ after all, they can save human lives,” Behfar believes.

The project is being advised by a team comprised of Professor Leena Ukkonen (TUT), Professor Lauri Sydänheimo (TUT), Ken Goldman (H-Cubed, Inc.) and Professor Shuvo Roy (UCSF).
