Dissertations
The remarkable amount of research being conducted on thermoelectrics gives the impression that this technology will have a bright future in power generation and temperature control systems. At the present time, thermoelectrics is applied widely for temperature control, but has not yet replaced conventional air-conditioning systems due to its lower performance. Currently, approximately 10% of annual vehicle fuel consumption corresponds to the air-conditioning system used to cool the vehicle cabin. Conventional air-conditioning systems cool the entire cabin; however, about 73% of a vehicle’s mileage occurs while the driver is the only occupant. These facts indicate the need for a single …

Elevated plantar pressure plays a major role in foot problems in diabetic patients. High pressures interrupt arterial blood flow, which is further compounded by the fact that diabetic patients lose sensory feedback from their feet, hence are not able to change their stance leading to unnatural pressure points. This can lead to dermal ulcerations, necrosis, and ultimately to partial or total amputation of the foot. This paper presents a preliminary design of an intelligent shoe-insert that automatically monitors critical foot parameters in diabetic patients. The objective is to collect information on plantar pressure, temperature and moisture and come up with …

Diabetic Mellitus is a disease caused either due to insufficient insulin produced by the pancreas or the body cells are unable to use the existing insulin. One of the main complications associated with diabetics is neuropathy, which is caused due to complete or partial loss of sensation in the feet and legs that lead to problems like inadequate delivery of nutrients and oxygen to the foot, which will cause healing impairment. In diabetic neuropathic subject, the hardness of foot sole soft tissue gives rise to plantar ulcer development. In this work, a biomechanical model is used to study the plantar …

Foot Ulcer in diabetic patients is a serious medical problem. A major contributor for the development of diabetic foot ulcers is a high, localized plantar foot pressure. It is believed that in diabetes the nerves in the extreme parts of the human body are damaged and cause deregulated blood flow, which may cause an insufficient blood supply. This can lead to a loss of feeling, change in shape of the feet, necrosis and ulcerations, and ultimately to partial or total amputation of the body part. The loss of feeling in the feet results in a loss of feedback to control …
A Lumped-Parameter Model To Investigate The Effect Of Plantar Pressure On Arterial Blood Flow In A Diabetic Foot, Carrie Hahn, Ajay Mahajan, Tsuchin Chu, Marco Schoen
A Lumped-Parameter Model To Investigate The Effect Of Plantar Pressure On Arterial Blood Flow In A Diabetic Foot, Carrie Hahn, Ajay Mahajan, Tsuchin Chu, Marco Schoen
Dr. Ajay Mahajan
This paper presents a lumped-parameter model for the big-toe region that investigates the effect of plantar pressure on the diameter of the blood vessels, specifically the arteries, in the presence of arterial and/or tissue changes. The model developed in this paper uses a multi-domain energy system approach to develop the lumped-parameter differential equations. Blood flow is modelled as fluidic flow through compliant pipes that have inertia, stiffness, and damping. The tissue material is treated as a soft compliant material that transmits the external force to the blood vessels. Conclusions have been drawn to show the effect of plantar pressure, tissue …
