发明名称 Heat transfer control for a prosthetic retinal device
摘要 A method for controlling heat dissipated from a prosthetic retinal device is described. A heat transfer device employs the Peltier heat transfer effect to cool the surface of the retinal device that faces the retina by dissipating/transferring collected heat away from the retina and towards the iris or front of the eye. According to one embodiment, a heat pump is formed in a second substrate on the retinal device. The heat pump is controlled by a temperature sense device that activates the heat pump, when a first predetermined temperature limit is exceeded. The temperature sense device deactivates the heat pump, when a temperature of the retinal device drops below a second predetermined temperature. According to another embodiment, a supply current of the retinal device may pass through the heat pump and a direction of heat transfer by the heat pump can be reversed, when the first predetermined temperature is exceeded.
