Shape‐Memory Materials: Shape‐Memory Microfluidics (Adv. Funct. Mater. 38/2013)

Electroactive Silk Fibroin Films for Electrochemically Enhanced Delivery of Drugs

“…For many biomedical applications in vitro, ex vivo and in vivo, the ability to deliver active ingredients in a controlled fashion is very appealing, and many stimuli have been investigated to achieve this (e.g., ionic strength, light, magnetic fields, pH, ultrasound, etc. ), [ 12,17–20 ] and a variety of stimuli‐responsive silk‐based materials have been reported. [ 21–28 ]…”

“…[16] For many biomedical applications in vitro, ex vivo and in vivo, the ability to deliver active ingredients in a controlled fashion is very appealing, and many stimuli have been investigated to achieve this (e.g., ionic strength, light, magnetic fields, pH, ultrasound, etc. ), [12,[17][18][19][20] and a variety of stimuli-responsive silk-based materials have been reported. [21][22][23][24][25][26][27][28] Electrical stimuli offer potential for precise control of medical devices, in part because of their ability to control the magnitude of currents/voltages and duration of pulses/intervals.…”

Synthesis and Properties of a New Chitosan‐Based Shape Memory Polymer and its Composites

“…[4] The temporary shape can be sustained for a long time after removing the external stimulus and force. In recent years, there is an increasing interest in developing shape memory polymers (SMPs) for a variety of applications such as controlled drug delivery, [5] tissue engineering, [6] wound healing, [7] endovascular clot removal, [8] self-tightening suture [9] and biomedical devices such as stents [10] catheters, [11] etc. To utilize SMPs in biomedical devices, the shape memory materials should possess biocompatibility and biodegradability behavior.…”

Shape memory behavior and mechanism of poly(methyl methacrylate) polymer networks in the presence of star poly(ethylene glycol)

“…Thermo-responsive shape memory polymers (SMPs) are those which have the capability of changing their shapes from a temporary shape to a permanent shape upon application of an external thermal stimulus. 1,2 They have attracted great attention of scientists and engineers in terms of their intrinsic advantages such as highly tunable properties, larger attainable strain, lower density, easier processing and lower cost, [3][4][5] which provide great potential for applications in biomedicine, 6,7 intelligent textiles, 8 aerospace engineering, 9 self-healing materials, 10 micro-optical or uidics devices 11,12 and emerging 4D printing. 13 In principle, thermally induced SMPs consist of netpoints and switches.…”
