A new type of pressure sensor has been developed that can withstand harsh deep-sea conditions. These sensors are compact, flexible, and potentially low in power consumption, removing the need for traditional bulky protective casings. Made from thin gold films encased in a soft film, these sensors can accurately measure a wide range of deep-sea pressures. Tests show these sensors work reliably under high pressure for extended periods, maintaining accuracy over repeated use. This makes them ideal for use in various ocean applications like tracking sea creatures, assisting divers, or integrating into soft underwater robotics.
