1. A sensor comprising:
a clip comprising an inner surface;
a capsule comprising a cavity and a sheath comprising a first portion and a second portion together enclosing the cavity,
wherein the sheath is made of a single electrically insulating material,
wherein the first portion is attached to the inner surface, the first portion comprises a first thickness, and is configured to be a rigid outer surface of the sensor,
wherein the second portion comprises a second thickness less than the first thickness and is configured to be a flexible outer surface of the sensor, and
wherein the capsule and the clip are configured to hold in vivo a tubular object of a living organism within an opening between the second portion of the sheath and the inner surface of the clip through direct contact of the tubular object both with the inner surface and with the second portion of the sheath to hold the tubular object firmly against the flexible outer surface of the sensor so that the second portion is bent by the tubular object;
wherein the opening between the second portion of the sheath and the inner surface of the clip is defined by a single projection of the clip, the single projection comprising a proximal end attached to the capsule and a distal end comprising a curved shape,
a transducer disposed in the cavity, the transducer being configured to detect in vivo an incoming signal received via the second portion, the incoming signal being a displacement of the second portion and indicative of a physiological parameter of the tubular object inside the living organism; and electronic circuitry disposed in the cavity and coupled to the transducer,
wherein the electronic circuitry comprises a wireless system, the wireless system comprising a power supply system, the power supply system configured to receive power wirelessly from an external radio frequency (RF) power source and supply power to operate the electronic circuitry, the external RF power source configured to be outside the living organism, and
wherein the electronic circuitry is configured to transmit a signal containing information about the physiological parameter obtained from the incoming signal.
