MTC’s Piezos Used for Wireless Power Transmission in EBR’s Wireless Pacemaker

Morgan Technical Ceramics (MTC) announced that its Bedford, Ohio site manufactures the piezoelectric ceramic materials used in EBR Systems, Inc.’s innovative new WiCS® Wireless Cardiac Stimulation System. The PZT (lead zirconate titanate) material made by MTC is critical to the efficiency of the WiCS system, which is powered by a battery with a 10-year lifespan.

ST Microelectronics Developing Implantable SOCs

Medical Product Manufacturing News announced that ST Microelectronics is developing ultra-low-power Systems On Chip (SOCs) suitable for implantable medical devices.  ST Microelectronics’ 65nm features a Vt of only 0.6V that can be used very near threshold.  The REISC processor consumes barely 10.8pJ/cycle at 0.6V.  This type of technology will certainly enable many new implantable devices
