Fraunhofer EMFT’s research and manufacturing portfolio includes piezoelectrically actuated silicon micro diaphragm pumps with passive flap valves. Research development in the field of microfluidics have been dedicated for many years to use micropumps generating positive negative pressures, as well delivering various media. However, some applications, only small amounts fluid need be pumped, com...

Introduction Blood pressure (BP) is one of the important vital signs that need to be monitored for personal healthcare. Arterial blood pressure is estimated from pulse transit time (PTT). This study uses two pulse sensors to get PTT. The aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. Materials and M...
