Abstract: A novel bioresorbable intracranial pressure sensor fabricated using readily available bioresorbable materials which are compatible with standard microfabrication technology is provided. The intracranial pressure sensor can also stay operational for a relevant time scale and can transfer data wirelessly.

Abstract: In certain examples, methods and semiconductor structures are directed Touched to a strain sensor integrated with a membrane substrate, a pressure sensor, and a plurality of material layers. The material layers are to integrate the strain sensor, the pressure sensor and the membrane substrate, with the pressure and strain sensors operating co-operatively to indicate, in response to a force applied to or towards the pressure sensor, characterization information of the force applied and of deformation of the membrane substrate. In a more specific example, the strain sensor and the membrane substrate are integrated with the aforesaid at least one of the material layers, and at least a portion of the pressure sensor and the membrane substrate are stacked to permit sensing of the force concurrently by the strain sensor and the pressure sensor.

Abstract: An example sensor apparatus includes two inductors with a first elastomer material between and at least one capacitor coupled to the two inductors. The at least one capacitor is configured, while in use, to at least partially wrap a circumference of an object and to exhibit a change in impedance in response to a pressure-manifestation change associated with the object, the change in impedance is to cause a change in the resonant frequency of the two inductors.

Abstract: The invention is related to a totally implantable cochlear implant having a transducer which is a piezoelectric vibration energy harvester to be mounted on the ossicular chain or the tympanic membrane to detect the frequency of oscillations and generate the required voltage to stimulate the relevant auditory nerves. The invention enables patients' continuous access to sound, since it eliminates the outside components of conventional cochlear implants. The invention also eliminates the problem of battery need, since the transducer generates voltage required to stimulate auditory nerves from the vibrations of ossicular chain. The transducer is fabricated using Microelectromechanical Systems (MEMS) fabrication techniques. The invention incorporates of two main parts, a transducer acting both as a frequency detector and an energy harvester, and electrodes to stimulate the auditory nerve inside the cochlea.
