This paper presents a new development of sensor systems which use liquid crystal droplet materials. This material is a flexible plastic sheet which can be readily polymerized to any thickness, size or form. Sensors formed from the material do not require sealing and can be fabricated as large, flexible plastic sheets, which can be or trimmed. The high stability of these materials makes it possible for them to be used in electric field sensors. An electric field sensor is prepared using liquid-crystal droplet materials.
