Researchers first cut from a silicon wafer with chemicals in a thin silicon. Through a transfer seal (rubber stamp), they will flip to the polymers or silk nano-silica film metal electrodes and wires, and then deposited on the membr ane, and wrapped the entire unit with epoxy coating.non absorbable suture
Researchers suture wire-bound on the two types of temperature sensors. One is the silicon diode current output varies with temperature; the other is to change its resistance value of platinum nano-film resistors with temperature. At the same time, the micro-heater is a simple gold filigrees, when current passes through them that is able to heat.
Rogers said all the materials of this device can be safe to use in humans, the biggest challenge is to become pliable and flexible suture. Silicon is brittle, so doing the nano-film as thin as possible and wound arrange them, is the key to flexible. The epoxy resin with the underlying silicon on the top of the suture between the polymer is also important. "When you bend the entire suture, the top bear tension and low-level exposure to pressure, but the middle position the force i s very small," Rogers said.surgical suture needle
The researchers have tested on mouse skin incision suture elasticity and toughness, but have yet to test temperature sensing and heating function in animals. They are also studying how the radio control device.
