Study of the temperature field in microchannels of a PDMS chip with embedded local heater using temperature-dependent fluorescent dye

2017

A functional double cone tube (DCT) array with gas trapping and high durability is developed in the application of artificial skin. A stereo-lithography system is employed to fabricate DCT made of acrylic resin. In an aqueous solution, a certain amount of gas can be trapped in the tube due to capillary force balance. Under applying an external load, internal stress is effectively released at the interface between top and base cones. In the tactile sensing investigation, softness and tackiness senses as an artificial skin are felt.

“…Some researchers employed so-called SD method. [1][2][3] However, in order to simplify, we propose a new method of tactile sensory evaluation with the pentagon-shaped graph. This original evaluation in this study was proposed to indicate a tactile sense visibly.…”

“…In this regard, the various studies concerning relationships between micro topological structure and human tactile sense have been focused. [1][2][3] Therefore, the purpose of this study is to develop a micro resist structure with tactile characters of the human and to propose its evaluation method, which gives ample consideration to variation of the tactile sense due to sweat, sebum and water influence. In this paper, we used this original tactile sensory evaluation for the pattern design of the microstructure which cleans up a sweat, sebum and water on a panel screen.…”

Tactile Senses Control by Contacting a Human Finger with Micro Resist Pattern Arrangements

Kunii

2014

A functional micro resists structures with tactile characters of the human are developed due to sweat, sebum and water influence. A new method of tactile sensory evaluation with the pentagon-shaped graph is employed. It is found that the micro pattern acts to wet and to feel smooth and comfortable by immersing some kinds of liquids. By the surface energy analysis, the tactile sensory evaluation can be explained at the point of wetting nature.

“…There is a need of local heating by micro systems such as heat actuator, µ-TAS and so on [1][2][3]. In particular, heat treatment for unit cell at relatively low temperature (~40 o C) is needed.…”

Local Heating System Integrated with Platinum Micro Heater and Photopolymer Microfluidic Channel

Noguchi

2013

Local heating system composed with micro heater and microfluidic channel is designed and fabricated. Micro heater made of platinum film is formed on a slide glass by radio-frequency magnetron sputtering and lift-off processes. Microfluidic channel is designed to surround the micro heater. A SU-8 epoxy-based negative photoresist is employed as micro channel material and patterned by lithography process. The micro heater has ability to heat over 350 o C at an electric power of 3.12W. Local heating property is evaluated by applying DC electric power. Heating area decreases 61.5% for micro channel filled with water by comparison with empty channel. Temperature of water in the micro channel is rise up 3.5 o C and heat absorption, which is estimated about 275.3µJ. The microfluidic channel with water is an effective method for local hearing. The local heating system with integration of micro heater and channel is one candidate which can apply to various fields such as biological and biomedical tools.
