Abstract
A micro-instrument suitable for property imaging in a body is less than one millimeter in each dimension. The micro-instrument includes a base having a first wall and a second wall, the second wall substantially circumscribing the first wall, and a lid connected with the base to form a cavity and the lid being temporarily deformable. Optionally, the lid can include a cantilever that is deformable. Also optionally, an electronic circuit can be attached with the micro-instrument. The micro-instrument can also be substantially spherical. An observable property of the micro-instrument varies as a function of a physiological property of the body.
