Kinetic inductance bolometers and calorimeters, each consisting of a kinetic inductance device (KID) suspended on a membrane and embedded in a resonant circuit, are being developed for applications such as planetary science, climate science, and X-ray spectroscopy. Arrays of these resonator-bolometers, each with a unique resonant frequency, are coupled to a single feedline, allowing many bolometers or calorimeters to be multiplexed using microwave readout. These devices potentially offer a combination of high sensitivity, large arrays, and broadband response not available from competing technologies.
