This technology describes multi-axial artificial muscle tissue, its formation method, and structure, created by gelling hydrogels containing muscle cells and extending and connecting them along different axes.
Conventional methods had limitations in the size and directionality of the tissues that could be manufactured, making it difficult to reproduce complex tissue forms such as cardiac muscle.
This technology reproduces complex muscle tissue with scalability and diverse directionality by independently forming modules with specific orientation along each axis and then integrating them.
This technology relates to a device for detecting ground subsidence, consisting of a subsidence sensor, a circuit board, a housing, and a cover, which is attached to a facility and connected to other units via cables.
Conventional single-sensor detection systems are prone to false alarms caused by noise or abnormal signals, making it difficult to reliably monitor large areas.
To address this, our technology connects and operates multiple detection units via cables, eliminating mutual sensor errors to provide precise and highly reliable ground subsidence detection.

This technology is a retrofitting structure designed to enhance the seismic performance of walls. It consists of a reinforcing member, which is placed in an area where the width-wise end of the wall has been removed and features pre-formed fixing holes, and anchors that are inserted into the fixing holes and wall installation holes to secure the reinforcing member to the wall.
Conventional seismic retrofitting for walls has faced limitations in achieving effective reinforcement, as it is difficult to securely fasten reinforcing materials to the wall and fill the gaps between them.
By placing the reinforcing member in the removed area, securing it with anchors, and filling the gaps, this technology can be applied to the seismic retrofitting of aging buildings to improve the seismic performance of their walls.
