AB  - We propose a wireless pressure sensor composed of a graphene sheet and a 
      transmitter coil integrated with a polydimethylsiloxane (PDMS) tube. The pressure 
      inside the tube was monitored wirelessly using an external receiver coil. We then 
      monitored the typical blood pressure range, 12(-)20 kPa, using this fabricated 
      sensor by changing the turn number of the receiver coil and the overlapping 
      length of the coils. Furthermore, we demonstrated wireless blood pressure 
      measurement by connecting our sensor to the blood vessel of a rat. Our results 
      suggested that this sensor can be easily inserted between an implantable medical 
      device and blood vessels for in vivo blood pressure monitoring. The proposed 
      wireless pressure sensor could also be suitable for monitoring in vivo implanted 
      medical systems, such as artificial organs and pump systems.
