Abstract
We have developed a passive pressure sensor intended primarily for int raocular pressure measurements. We have earlier reported the basic sen sor and system design concepts, and initial experimental results. In t his paper we present a method to improve the Q value of the sensor ele ment. The first experimental results in vivo are also reported. The ex ternal detector works adequately for sensor elements with a Q value ab ove 100. The system has been tested in vitro in gas and liquid, where a sensitivity of 4 mV/mmHg was reached.
