2. 1. Towards a tactile artifical hand

   Author : Ulrika Wijk; Malmö Handkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amputation; upper limb; phantom hand map; sensory feedback; referred sensation; hand prosthesis; body ownership; tactile sensation;

   Abstract : Amputation of a hand is a life-changing event, and the loss of motor and sensory functions leads to disability and has devastating effects on the individual. What is normally performed using two hands must be solved with only one, and the loss also affects body balance and body posture. READ MORE

4. 2. Touching on elements for a non-invasive sensory feedback system for use in a prosthetic hand

   Author : Pamela Svensson; Avdelningen för Biomedicinsk teknik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensory feedback; amputation; referred sensation; non-invasive feedback; upper limb prosthetics; body ownership;

   Abstract : Hand amputation results in the loss of motor and sensory functions, impacting activities of daily life and quality of life. Commercially available prosthetic hands restore the motor function but lack sensory feedback, which is crucial to receive information about the prosthesis state in real-time when interacting with the external environment.

5. 3. Adhesion and Friction - a Study on Tactility

   Author : Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

   Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

6. 4. Hand cooling, protection and performance in cold environments

   Author : Qiuqing Geng; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Abstract : This dissertation presents experimental data on hand/finger cooling responses and performance in cold environments with and without gloves. The first part concerned studies of hand/finger cooling behaviors under various cold conditions. READ MORE

7. 5. Molecular mechanisms of synaptic transmission and plasticity in spinal sensory pathways

   Author : Max Larsson; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; electron microscopy; synaptic plasticity; synapse; pain; spinal cord; hyperalgesia; Neurologi; neuropsykologi; neurofysiologi;

   Abstract : An intense, potentially tissue-damaging (noxious) stimulus may lead to enhanced pain sensation of subsequent noxious stimuli (hyperalgesia) and to the perceiving of innocuous stimuli as painful (allodynia). This is thought to result to a large extent from strengthening of synapses established by primary afferent fibers onto spinal cord dorsal horn neurons. READ MORE
