—Nowadays, most manufacturers and offices handle
and use a large amount of liquid (water, seasonings, oil, etc.)
every day to produce products and provide services to their
customers. In general, liquid sensing devices are installed outside of a tank to detect liquid leakage more quickly. Authors
considered that the transparent liquid sensor has potential
needs from customers because of the existence of several types of transparent tanks, but currently, there are no sensors with transparency. In this paper, the 2-dimensional flexible transparent liquid sensing device is proposed. This device was
successfully created with high light-transmission rate (84.9%), and could detect familiar liquids (e.g., tap water, distillated
water, weak acid/alkali liquid, and strong acid/alkali liquid)
with the exception of low electrical conductivity liquids (e.g., oil
and alcohol). This sensing unit can be provided to the market at an affordable price by using printing technologies.
