1. 11. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

   Författare :Rohit Chandra; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

   Sammanfattning : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. LÄS MER

3. 12. A Novel Bone Conduction Implant System

   Författare :Hamidreza Taghavi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

   Sammanfattning : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

4. 13. Studies On Design of Near-Field Wireless-Powered Biphase Implantable Stimulators

   Författare :Yonatan Habteslassie Kifle; Jacob Wikner; Atila Alvandpour; Sebastian Bader; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Portable and implantable electronics are becoming increasingly important in the healthcare sector. One of the challenges is to guarantee stable systems for longer periods of time. If we consider applications such as electrical nerve stimulation or implanted ion pumps, the requirements for, e.g. LÄS MER

5. 14. Implantable bioartificial hybrids for targeted therapy in the central nervous system

   Författare :Lars U Wahlberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The rapid increase in the understanding of the CNS at the molecular level has brought us new knowledge and tools to attempt to locally manipulate the CNS microenvironment and thereby introduce reparative and ablative molecular therapeutic approaches in focal areas of the CNS. This targeted therapy will require neurosurgical intervention for the injection and implantation of cells, viral vectors, or drug release systems. LÄS MER
