Provided is an adaptive strap for brassieres having at least one adaptive material layer () having a first strength modulus x during static loading and a second strength modulus of at least 2× during dynamic loading of at least approximately 3 Hz oscillation. The adaptive layer () is sandwiched between two or more elastic fabric layers (). The adaptive strap is extendable up to 100% of its initial length during low wearer activity but is extendable not more than 50% during vigorous wearer activity, providing support during exercise and comfort during daily use. In one aspect the adaptive material is a reaction product formed by reacting a silanol terminated polydimethylsiloxane, polymer matrix, boric acid and optional fillers. The adaptive material () is cured in situ within the elastic fabric layers ().

The present disclosure provides a flexible electric generator and methods for fabricating the same. The flexible electric generator comprises a flexible triboelectric layer covering the electrode layer of a flexible piezoelectric generator that enhances output power by combining piezoelectric effect and triboelectric effect. The reliability of the flexible electric generator under bending is also improved due to the presence of the flexible triboelectric layer. The fabrication methods of the disclosed flexible electric generators are simple, thereby enabling large-scale manufacturing.

A low printing temperature thermoplastic filament composition for fused filament fabrication 3D printing is described. The filament includes polycaprolactone in an amount from 70 to 90 wt %, at least one thermoplastic polymer having a melting temperature between approximately 60&#xb0; C. and approximately 90&#xb0; C. in an amount from approximately 10 to 30 wt %, at least one antioxidant, and at least one plasticizing agent. This 3D printing filament can be printed out at temperatures below 100&#xb0; C. and no heated print bed is needed, which saves energy and minimizes the complexity of 3D printer. Besides the low printing temperature, this 3D printing material is bio-friendly which makes it safe for household use.
