Electric stone

Tourmaline was named as "Electric stone" by Linnaeus Carolus (1707-1778).

Tourmaline

The Sinhalese word "Turamali" became "Tourmaline" in 1703 as the scientific name. All the electric stones were called as "Schrol" until that year, while only opaque ones are now called so. (1)

Pyroelectricity

Brewster named electric charge generated when heat is applied as "Pyroelectricity" in his paper published in 1824 (2).

Piezoelectricity

Hankel named electricity generated when pressure is applied as "Piezoelectricity" in 1881. This is because he believed the electricity had different characteristics from that generated without pressure. (3)
