Researchers at Nanyang Technological University in Singapore have announced the development of a new, low viscosity liquid gel adhesive. The adhesive can be applied with precision, and curing is activated by exposure to electric current. By varying the voltage and duration of the current, the adhesive is exposed to, adhesion can be fine-tuned.
The new adhesive can be used in medical device manufacture as well as in automobile and consumer goods production. There are also biological devices for which adhesives that are cured using heat or light are unsuitable or difficult to use. These include bioelectronics and polymer electronic devices that are attached to living tissue.
The bonds formed using the new adhesive are strong, and demonstrate high sheer strength while providing a high degree of elasticity. The tunability of the adhesive will allow it to handle specific vibration frequencies and create bonds that match the flexibility and firmness of living tissues.
