- Cat's-whisker_detector abstract "A cat's-whisker detector (sometimes called a crystal detector) is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral (usually galena) to make a crude point-contact rectifier. Developed by early radio researchers Jagadish Chandra Bose, G. W. Pickard and others, this device was used as the detector in early crystal radios, from about 1906 through the Second World War. It gave this type of radio receiver its name. It was the first type of semiconductor diode, and in fact, the first semiconductor electronic device. The term cat's whisker was also sometimes used to describe the crystal receiver itself. Cat's whisker detectors are obsolete and are now only used in antique or antique-reproduction radios, and for educational purposes.".

- Cat's-whisker_detector caption "A "Perikon" detector, 1914. Instead of a wire-to-crystal contact, this had a crystal-to-crystal contact. The bornite crystal ' on the adjustable arm was moved forward until it touched one of the zincite crystals on the carousel '. Multiple zincite crystals were provided because the zincite was vulnerable to damage from atmospheric electricity.".
- Cat's-whisker_detector caption "Carborundum detector. This used a metal clamp contact instead of a delicate cat's whisker, so carborundum detectors were used in military and shipboard stations where vibration could be expected.".
