elopment of Poly Vinylidene Fluoride (PVDF) sensors
for transducer applications
Year of Development: moisture, most chemicals, oxidant
¡¡ Adhesiveness: Can be glued with
PVDF Films – 2005-2007
PVDF Sensors – 2009-2013 commercial adhesives
Application Level/Scale of Development:
TRL- 7
¡¡ Sensors: Accelerometer for sens-
ing vibration, pressure sensor for Intellectural Property Rights (IPR) :
pressure mapping of aero-wing
and measuring dynamic pressure Patent No 266633, May 2015.
of rotating blades, structural health
monitoring and acoustic emission, Market Potential
detonator for mines.
Global Current Transducer Market is
¡¡ A ctuator: Flapping wing for micro projected to reach USD 683.98 Million
air vehicle in 2023, growing at a CAGR of over
3% during 2018-2023. Increasing
¡¡ C ommunication: SONAR in sea importance on renewable resources,
water communication growing industrial automation,
increasing demand for electric vehicles
¡¡ E nergy Harvesting: Uni-morphs, and increasing use of energy storage
Bi-morphs, Multi-morphs and ar- machines are the major factors
ray of Uni-morphs propelling the growth of the global
current transducer market.
Salient Technical Features
Major Raw Materials to be
