• Color photography was invented by Karl Schinzel in Opava-Komárov in 1905. ^[2]
• Blood types were discovered by Jan Janský in Prague in 1907. It is considered the most important Czech medical discovery. ^[3]
• Kaplan turbine was invented by Viktor Kaplan who obtained his first patent for an adjustable blade propeller turbine in 1912.
• Tent with wooden sides was invented by the Czech Scout Association in 1913. ^[4]
• String bag was invented by Vavřín Krčil in Žďár nad Sázavou in the 1920s. ^[5]
• Polarography was invented by Jaroslav Heyrovský in 1922. ^[6]
• Cabin motorcycle (Dálník) was invented by Jan Anderle during 1930s. ^{[7] [8]}
• Versatil pencil was invented by Czech company Koh-i-Noor Hardtmuth in 1937. ^{[9] [10]}
• Silon textile material (synthetic fiber) was invented by Otto Wichterle during 1940s.
• Water jet loom is a shuttleless loom, which allowed much faster operation. It was invented and patented by Vladimír Svatý in 1950. First machine was made in Zlín, mass produced in Semily since 1955. ^[11]
• Soft contact lenses – Drahoslav Lim and Otto Wichterle invented Polyhydroxyethylmethacrylate (pHEMA) for biological use. Wichterle thought pHEMA might be a suitable material for a contact lens and gained his first patent for soft contact lenses. By late 1961, he succeeded in producing the first four pHEMA hydrogel contact lenses on a home-made apparatus.
• Sobering-up station was invented by Jaroslav Skála in 1951. ^[12]
• Remoska is a small portable electric oven with the cooking element housed in the lid of a pot that consists of a Teflon-lined pan and a stand in addition to the lid mounted heating element. It was developed by the Czech electrical engineer Oldřich Homuta in the 1950s.
• Czechoslovak pharmacologist Frank Berger invented Meprobamate, the first tranquilliser and Felbamate, an anticonvulsant used in the treatment of epilepsy. ^[13]
• Semtex, a general purpose plastic explosive, was invented in the late 1950s by Stanislav Brebera and Radim Fukátko, chemists at VCHZ Synthesia.
• Kurt Lehovec invented p–n junction isolation a method used to electrically isolate electronic components, such as transistors, on an integrated circuit (IC) by surrounding the components with reverse biased p–n junctions.
• Shock-absorbent barrel used for stunts was developed by Karel Soucek. ^[14]
• Tenofovir disoproxil was synthesized by Antonín Holý at the Institute of Organic Chemistry and Biochemistry of the Czechoslovak Academy of Sciences in Prague. The patent filed in 1986 makes no mention of the potential use of the compound for the treatment of HIV infection but claims activity against herpes simplex virus.

21st century

• W0 constant was invented by Czech scientist Viliam Vatrt in 2011. ^[15]
• Solar Air Water Earth Resource (S.A.W.E.R.) is an autonomous system for obtaining water by condensation from the air. The project was developed by researchers of the Czech Technical University in Prague and the Czech Academy of Sciences. ^{[16] [17]}
