  • Patent number: 11172731
    Abstract: Dual-layer insole apparatuses for diabetic foot lesion prevention and related methods are provided. Some insole apparatuses have a body defining a plurality of cavities configured to be coupled to a fluid source. The fluid source can deliver fluid to vary internal pressures of the cavities. The body further defines an insole-shaped structure.

  • Publication number: 20210220206
    Abstract: This disclosure includes manipulating apparatuses and related methods. Some manipulating apparatuses include an actuator having a semi-rigid first segment, a semi-rigid second segment, and one or more flexible cells disposed between the first segment and the second segment, where the actuator is configured to be coupled to a fluid source such that the fluid source can communicate fluid to vary internal pressures of the one or more cells, and where each cell is configured such that adjustments of an internal pressure of the cell causes angular displacement of the second segment relative to the first segment.

  • Patent number: 10653538
    Abstract: This disclosure includes bubble actuator arrays and methods for making and using the same. Some bubble actuator arrays include a first flexible layer having a substantially flat first portion and a plurality of second portions that protrude away from the first portion to define chambers, a flexible second layer sealed to the first layer to define a plurality of cells in the chambers and between the layers, and where the array can be coupled to a fluid source such that the internal pressures of the cells can be varied. Some of the present methods include adjusting with a processor and fluid source the pressure in the cells of an array. Others of the present methods include placing sacrificial material into chambers of a molded first layer such that a plurality of cells is formed when a second layer is molded coincident to the first and the sacrificial material is removed.
